spanner: fix failing tests
- Skip two chronically flakey tests.
- Remove t.Parallel: this slows down the tests, but makes them
more reliable. Increase test timeout to compensate.
- Increase recommended node count. This reduces the amount of
ResourceExhausted RPCs.
- Fix waitFor error to actually print time, instead of a
memory address.
- Add healthcheck stop to cleanup.
- Standardize cleanup name.
- Increase query timeout to 5m across the board to compensate
for multiple tests running queries in the instance.
