Currently, the `admin-openrc` file is being generated by the init
container (clients-init) via the redirection operator `>>`.
This can unnecessarily populate the file if the init container runs two
or more times. Therefore, we can fix this by using the redirection
operator `>` instead of `>>`.
Test Plan:
PASS - Build stx-openstack-fluxcd-helm package
PASS - Build stx-openstack helm charts
PASS - Apply/upload stx-openstack
PASS - Manually delete one of the clients pod and wait for it to respawn
PASS - Verify that admin-openrc does not contain additional lines:
$ cat /var/opt/openstack/admin-openrc
PASS - Remove/delete stx-openstack
