All packages, except for `cmd` and `internal`, have been moved into a new `v1` root package.
Old packages are kept for backwards-compatibility reasons. All contained code is replaced with simple type aliases and proxy functions to `v1` implementations.
Old packages default to the Rego v0 syntax, new `v1` packages default to the Rego v1 syntax.

Earlier a snapshot bundle would describe the full state of OPA's
policy/data and any update would require first erasing the state from
the existing bundle and then activating the new bundle.
This commit introduces a new bundle type called "delta".
Delta bundles contain patches to data instead of snapshots.
They allow users to efficiently make updates to OPA's data
cache.

This commit introduces the idea of manual triggers to trigger
plugins. Currently plugins such as discovery, bundle, decision log etc.
perform their functions in a timer-based loop. For example, the bundle
plugin periodically checks for new bundles by polling a remote server.
This change adds the ability to trigger a plugin thereby allowing callers
to control when a bundle download happens, when a decision log is
uploaded etc. The periodic mode is still the default for the plugins.
This feature allows callers to trigger individual plugins. Plugins perform
their functions and then report back to the caller when done.

Earlier the downloader package only supported the http
short polling technique where the client sends periodic
requests to the server to fetch bundles. A drawback of this
method is that a low polling frequency could add unnecessary
burden on the server and network.
This commit adds support for http long polling which helps
to minimize server/network resource usage and also reduces
the delay in delivery of updates to the client.

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
