Anders Eknert 968d49de3d Injectable logging implementation
Refactor logging to allow providing custom logging implementations to plugin
manager. This should allow us to keep logging as it is when running OPA as a
server, while injecting noop-loggers or custom, provided loggers for SDK client
implementations.

Fixes #3180

Anders Eknert 36ba4454e8 OAuth2 JWT bearer grant type and JWT client auth
Allow OPA to issue JWT's which it uses to authenticate a configured
OAuth2 client, as described in RFC7523. This replaces the client_secret
as the actual credential and allows for either using an entirely new
grant type called "JWT bearer", or using the previously supported
client_credentials grant type, only with the client_secret replaced
by a signed JWT. This change covers both scenarios described in
RFC7523.

Other changes made to accomodate this feature:

- Add `private_key` attribute to keys struct to allow for both public and
private keys to be stored there.
- Refactored the keys configuration struct and logic to its
own package no longer coupled to bundles.

Closes #3055

Grant Shively a1d8381fc8 plugins: inter-query cache config discovery
InterQueryBuiltinCacheConfig now responds to the plugin manager's reconfigure event, which allows cache config to exist in discovery config. Previously, cache config would be ignored if it was only declared in discovery config.

Related to #2978.

Ashutosh Narkar 7f65b04561 Add a new inter-query cache to cache responses across queries
This commit adds a new inter-query cache that built-in
functions can use to cache responses across queries.

The OPA config includes a new "caching" field that can be used
to set the size of the cache. By default there is no limit.

This change also updates `http.send` to optionally utilize the
inter-query cache.

Ashutosh Narkar 338583c18a Add support for OPA bundle signatures
These changes add support for digital signatures for policy bundles which
can be used to verify their authenticity.

Bundle signature verification involves the following steps:

* Verify the JWT signature
* Verify the files in the JWT payload exist in the bundle
* Verify the file content of the files in bundle match with those in the payload

This commit adds a new `sign` command to generate a digital signature for policy bundles.

For more details, run "opa sign --help"

The signatures generated by the 'sign' command can be verified by the
'build' command. The 'build' command can also sign the bundle it generates.

The 'run' command can verify a signed bundle or skip verification altogether.

OPA 'sign', 'build' and 'run' can be used to
sign/verify bundles in bundle mode (--bundle) mode only. Verification
can be also be performed when bundle downloading is enabled.

Torin Sandall 62f292b6e3 internal: Refactor load/store/compile implementation
This commit refactors the load/store/compile implementation that used
to live inside the runtime package. Specifically:

* Move init-time file loading logic into separate internal package
  (initload) along with store/compile logic. Add tests around
  load/store/compile that don't require the entire Runtime object.
  This also avoids duplication of the "version overwriting" logic.

* Move store/compile calls into the manager. This avoids the need for
  two compile operations on startup.

Torin Sandall f962990758 plugins: Fix race between manager and plugin startup
This change fixes a race condition in the manager that was caused by
registering the storage trigger _after_ the plugins had been
started. The problem was that if the bundle plugin was able to
download and activate before the trigger registration in the manager
went through, the store and the manager would be out-of-sync after
startup. The bundle would activate successfully but the plugin
manager would not see the change. This meant that the server health
check, status plugin, etc. would report successful activation and
clients using either of those APIs for synchronization could start
querying. If they executed a query within this window, virtual docs
would not be visible because the plugin manager would not yet have a
compiler to return to the server. Similarly, if clients queried the
v1/policies API they would see the raw policy contents but no AST
(since the latter is retrieved from the compiler.)

To remove the race condition the plugin manager simply registers the
trigger before starting any of the plugins. This ensures that it sees
all changes made by any of the plugins.

Torin Sandall e4ae6a70e5 bundle: Cache compiler on storage context
These changes update the manager and bundle plugin to avoid parsing
and compiling modules during the manager's trigger callback. Since
policy queries are blocked while triggers execute, it's adavantageous
to cache the compiler that is obtained during bundle activation and
reduce the work done in the trigger callback.

Also, as part of these changes, the bundle plugin incorporates
remaining modules when it recompiles. This ensures that remaining
modules are correct.

Torin Sandall 2d425494aa Refactor discovery implementation
These changes refactor the discovery implementation a bit to improve
test coverage and remove duplication of common logic shared with the
bundle plugin.

Specifically, the downloading logic has been moved into a separate
package that is shared by bundle and discovery. Second, test coverage in
the discovery implementation is increased from ~15% to ~85%.

These changes also include a few functional improvements:

- The default decision paths can be updated dynamically
- The decision logger can be enabled dynamically
- Discovery downloading errors are reported in status updates
- Discovery bundle is evaluated with all runtime params
- Custom plugins can be created dynamically
- Status updates include both discovery and bundle status

Ashutosh Narkar 2185f1eb86 Add support for configuration discovery
Previously OPA configuration for bundle downloading, status reporting, etc. had to be supplied in a configuration file on startup. With these changes, OPA can be configured to download a bundle that generates the OPA configuration. This allows OPA to boot with minimal configuration and dynamically update that configuration on-the-fly making it much easier to manage large deployments of OPAs for different use cases within the same system.

* Add support for specifying services as object

Previously the services configuration had to be specified as an array,
for example:

services:
- name: foo
  url: https://example.com

In some cases, it's easier to structure the configuration as an object.
Specifically, the Helm package manager does not allow you to override
values nested under arrays. These changes allow the services
configuration to be structured as an object:

services:
  foo:
    url: https://example.com
