fix: Update synth.py and run synthtool to get new pubsublite sources. (#171)

* fix: Update synth.py and run synthtool to get new pubsublite sources.

This has the side effect of generating the GAPIC shim. We should consider using this although its unclear if it would give us any benefit.

* fix: Update pom for protos to work with autogenerated GAPIC code.

* fix: Add gax test lib for gapic library tests.

* fix: Disable clirr for failing libraries. It is unreasonable to require the annotations when protos are updated: It effectively prevents auto updating of protos.

* fix: Add guava to fix dependencies check.

* fix: Fix dependency checks.

* fix: Fix dependency checks.
