bootstrap containers need KOLLA_BOOTSTRAP=True

[Emilien Macchi]

There is no need to run bootstrap containers on the controllers that aren't the bootstrap node.
It can produce failure logs which can cause confusion to the operators when debugging even if the failure isn't critical.

    Add KOLLA_BOOTSTRAP=True to 2 bootstrap containers

    keystone_bootstrap and mysql_sync_credentials are containers which need
    to be run on the bootstrap node only, there is no need to run them on
    other controllers. It avoids useless verbosity when they fail to
    execute.
