This patch adds a build-time test for the metadata replication feature.
Note that this is not a complete test, in particular it does not
verify that the database was synched correctly at the slave.
But it verifies quite a bit.

Test for metadata replication (incomlete - does not verify
key integrity, just that server thinks it went slave).
