Enable for MariaDB failover

[ghost]

Existing scripts should be adapted to also support replication to a MariaDB instance.

It would certainly be good for the enhancements listed in #5 and #6 to be incorporated into the MariaDB version from the start.

[gregcorbett]

Having some easy means of stopping the import from running would be useful.

Perhaps the presence of something like /etc/gocdb/nofailoverimport cause the failover scripts to exit without doing anything.

Do you want this to exit as if an error, which it isn't really, or pretend that it 'completed ok'?

[gregcorbett]

Maybe it could output something like the below.

not doing anything with /etc/gocdb/nofailoverimport set
cat contents of /etc/gocdb/nofailoverimport

I think exit and an error is probably for the best, because the intention of the caller was to presumably update the failover DB and that would not be done in this case.

This has been done
