Problem

When running tests with gcp-starter env. in java sdk, there were a couple of issues that needed to be addressed. In particular:

1. Create and listIndexes wasn't working.
2. Queries parameter was deprecated but the proto file wasn't updated with a warning.
3. After upserting vectors into an index of gcp-starter env., there was some latency in querying the vectors which caused tests to fail.

Solution

This PR addresses the following:

1. Fixed path for gcp-starter env to address the createIndex and listIndexes issue in gcp-starter env.
2. Add deprecation tag for queries parameter of VectorRequest in vector_service.proto file.
3. Added assert with retry mechanism function to make sure the tests are passing even though they fail for first couple of times. Given gcp-starter is a free-tier and not as performant as pod indexes, the retry mechanism will help ensure passing of the tests.
