Git tags for minor versions

[jmillikin]

There's currently two Git tags defined in bazelbuild/remote-apis:

• Tag v2.0.0 is commit e77c4eb and is (hopefully) what implementations mean by SemVer { major: 2 }.
• Tag 4ac0011 is commit 4ac0011 and is of unknown meaning.

The comments in remote_execution.proto refer to changes in minor versions v2.1, v2.2, and v2.3 which are not tagged. This makes it difficult to determine which behavior a conforming implementation should have at each version.

Given that there's now multiple APIs specified, and multiple versions of the Remote Execution API, would it be possible to add additional tags? For example:

• execution/v2.0, execution/v2.1, execution/v2.2, and execution/v2.3 that can be used as stable references for a given version of remote_execution.proto
• asset/v1.0 and logstream/v1.0 for similar purposes in the remote_asset.proto and remote_logstream.proto files.
