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.

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.

With #1715 we updated opa.runtime() to include the OPA semantic
version in the output. This change extends that to include the build
commit which is useful for development purposes.

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

These changes add support for accessing runtime information inside of
policies. In some cases, policies need to access environment variables
or configuration that OPA was booted with. These changes add a built-in
function that allows policies to gain access to this information. The
built-in function itself is relatively trivial. Most of the required
changes were plumbing the runtime information from the entrypoint down
into the evaluation engine. The alternative would have been to introduce
a global variable containing this information however that would be have
been harder to reason about in library integrations.
Fixes#420
