0001-Restart-memcached-after-koha-remove-if-needed.patch

After running koha-remove, stale data remains in within the memcached server.

Say if an instance is deleted then recreated immediately, changed data such as
database credentials isn't loaded into the cache, resulting in strange,
difficult to troubleshoot problems.

The solution would be to flush memcached cache at the end of koha-remove.

The most straightforward method to do this is simply restart the service.

See attached patch.
