Revert back to using nightly base images instead of pinning to 1.12.1. Pinning the docker image had led to uncaught errors in the past. Instead, we should be using nightly to make sure release tests will work on the most up to date versions of docker/cluster envs. If there are any test failures, the underlying issues should be fixed rather than pinning the docker image.

This adds "environments" to the release package that can be used to configure some environment variables. These variables will be loaded either by an `--env` argument or a `env` definition in the test definition and can be used to e.g. run release tests on staging.
Currently, `name:many_actors` matches e.g. `many_actors` and `many_actors_smoke_test`, but it should just match one test. Thus we should use `re.fullmatch` instead of `re.match` (which would require `name:many_actors.*` to match both.
OSS release tests currently run with hardcoded Python 3.7 base. In the future we will want to run tests on different python versions.
This PR adds support for a new `python` field in the test configuration. The python field will determine both the base image used in the Buildkite runner docker container (for Ray client compatibility) and the base image for the Anyscale cluster environments.
Note that in Buildkite, we will still only wait for the python 3.7 base image before kicking off tests. That is acceptable, as we can assume that most wheels finish in a similar time, so even if we wait for the 3.7 image and kick off a 3.8 test, that runner will wait maybe for 5-10 more minutes.
Currently nightly tests are unable to finish in a day because of concurrency group limit on `large` tests. This is an attempt to adjust the limits so buildkite can run / finish more tests. I will observe which tests fall into the `enormous` group and adjust the test resource / concurrency group limits again.
Currently concurrency groups are always calculated based on the full test cluster compute. Instead, smoke tests should use the smoke test cluster compute.
What: Adds a setting "prefer_smoke_tests" to the Buildkite settings. With this, user can specify to kick off smoke tests, if available.
Why: The filtering interface of the release testing dialog is a bit complicated at the moment - in order to kick off smoke tests, users have to know with which frequency they are configured to run. Instead users should usually just filter the tests they want to run (using frequency ANY) and optionally specify to run smoke tests, if available.
Support filtering tests by test attr regex filters. Multiple filters can be specified with one line for each filter. The format is attr:regex (e.g. team:serve)
Currently, all buildkite runs report per default. Instead, we only want to report when running scheduled builds or when specifically overriding this behavior.
E.g. long running tests run on small clusters (often 8 CPUs) but block other jobs for a long time. We should thus add more granularity to the concurrency groups.
Additionally, limits have been slightly adjusted to make more sense (e.g. 8 GPUs are now small-gpu, 9+ GPUs large-gpu, instead of 7 for small-gpu and 8 for large-gpu).
This PR reduces the concurrency limit. Based on the back of envelope calculation, the current concurrency limit can easily exceed the service quota.
Given large == 2048 vCPUs, it will use about 20K vCPUs, which is slightly larger than the limit.
This PR adds concurrency groups to Buildkite release test runs with new release test package. Five concurrency groups are defined (large-gpu, small-gpu, large, medium, small). If not specified manually, concurrency groups are inferred from used cluster resources.

Adds a unit-tested and restructured ray_release package for running release tests.
Relevant changes in behavior:
Per default, Buildkite will wait for the wheels of the current commit to be available. Alternatively, users can a) specify a different commit hash, b) a wheels URL (which we will also wait for to be available) or c) specify a branch (or user/branch combination), in which case the latest available wheels will be used (e.g. if master is passed, behavior matches old default behavior).
The main subpackages are:
Cluster manager: Creates cluster envs/computes, starts cluster, terminates cluster
Command runner: Runs commands, e.g. as client command or sdk command
File manager: Uploads/downloads files to/from session
Reporter: Reports results (e.g. to database)
Much of the code base is unit tested, but there are probably some pieces missing.
