spanner: Create and drop a test instance for each integration test run

Instead of using a fixed Spanner instance for all integration test runs,
this will create a new instance specifically for one test run and create
all test databases on the temporary instance. The temporary test instance
will be deleted after the test execution. The cleanup method will also
delete any old test instances that might have been left behind by a
previous test run, if these are more than 24 hours old.
Each integration test will create a new database, but will not drop it,
as the instance will be deleted at the end of the test run anyways. This
reduces the chance that a test case times out while dropping a database.

Updates #1571.
