Remove mock integration tests.

These tests have not been maintained for several years, i.e. no tests for new features have been added. They are highly duplicative of the unit tests but do have the advantage of mixing in different storage drivers. They were allowed to remain because they were not doing any harm even if they were probably not doing any good.

However, the real integration tests (that run directly against PostgreSQL) also test storage drivers and have been updated with new features over time. The real integration tests are now being migrated to C and as part of that effort the mock integration tests need to be removed or migrated, and they do not provide enough value to migrate.

Remove all mock integration tests and a leftover Perl performance test.
