Fixes TestCheckAndMutateRow_NoRetry_TransientError
Before fix:

=== RUN   TestCheckAndMutateRow_NoRetry_TransientError
    checkandmutaterow_test.go:252: 
        	Error Trace:	/usr/local/google/home/bahaaiman/Documents/cfdb-workspace-01/cloud-bigtable-clients-test/tests/checkandmutaterow_test.go:252

        	            	actual  : 0
        	Test:       	TestCheckAndMutateRow_NoRetry_TransientError
    checkandmutaterow_test.go:253:

        	Test:       	TestCheckAndMutateRow_NoRetry_TransientError
--- FAIL: TestCheckAndMutateRow_NoRetry_TransientError 

After fix:

=== RUN   TestCheckAndMutateRow_NoRetry_TransientError
--- PASS: TestCheckAndMutateRow_NoRetry_TransientError (0.01s)

We don't know if the conditional mutation has been applied so we can't retry them.
Updated the retry to match Java's retry settings:

As a general comment, and not something to be done on this PR (and certainly not blocking): should we consider decoupling this kind of configuration from each method implementation and instead have a central configuration (like we do on the java client)?
