Allow to reuse an existing global refdb database when running tests

Database creation and especially scheme initialization can take very
long time, up to a minute based on my observation. By allowing to reuse
and existing database we significantly reduce test run time. Use
SPANNER_DATABASE environment variable to specify a database.

Example:

  bazelisk test \
  --test_env='GOOGLE_APPLICATION_CREDENTIALS=/path/to/the/key.json' \
  --test_env='SPANNER_INSTANCE=test-instance' \
  --test_env='SPANNER_DATABASE=test-global-refdb' \
  --test_tag_filters=spanner-refdb //...

Note that the specified database doesn't even need to exist. It will be
created if necessary. However, it will not be dropped when the test
run finishes, leaving it ready for a next test run.
