We have seen issues with dangling threads in Armada. This is likely due to a bug [0] in the version of gRPC that we were pinned to. This patchset: - moves us to the latest versions of the gRPC python libraries which add a new `channel.close()` method to cleanup channels. - implements the python context manager api in the tiller handler - uses the context manager api to explicitly scope tiller channel creation and cleanup to each Armada API and CLI call. This also fixes a couples issues with error handling introduced in [1].
