Fix memcached doesn't start issue

JIRA: -

Sometimes memcached does not start after installation finished,
which will cause issues like openstack dashboard open instance
console failure.

This patch add memcached restart notify during package installation
and add memcached to cron service-status-check task's config file:
/opt/service
