Remove the stats protos from ConnectivityService until tests are added

Adding service-connectivity-stats-protos creates a lot of extra proto
apis. Currently we don't provide any test cases for these apis.
This affects the coverage of the connectivity coverage test by 5%.
So remove the protos in ConnectivityService until all tests for proto
apis are added.
