Packaging: Gnocchi renaming broke systemd services

[Emilien Macchi]

Gnocchi packages & services were renamed: https://review.rdoproject.org/r/#/c/10736
But now the services don't start anymore with the old name, even though Alias is used in the service unit file.

It's breaking scenario001 in both TripleO & Puppet promotions CI.

To make it work, we had to run:

systemctl disable gnocchi-metricd.service
systemctl disable gnocchi-statsd.service

systemctl enable gnocchi-metricd.service
systemctl enable gnocchi-statsd.service

So it's probably a packaging bug...

So the problem is that Puppet tries to enable the service with the old name but systemd expects the new name so it can creates the symlinks.
Which means "Alias" in the .service file only works after having enabling the service with the new name.

We're disabling Gnocchi everywhere until we promote.

In fact, we decided to revert because it affects all RDO users, not only TripleO and Puppet.
Gnocchi devs will have to figure out a backward compatible way that actually works.

We're reverting now so we can continue to promote Puppet & TripleO CI.
We'll let Gnocchi folks decide how to move forward. Multiple options:

- disable Gnocchi in TripleO & Puppet, rename gnocchi packages/services in puppet-gnocchi and promotion will pass.
- ship multiple .service files (but can cause issue, not tested).

In any case, we don't want to take decision for them, so we revert now, since it's blocking the production chain.

I proposed a new version without this issue: https://review.rdoproject.org/r/#/c/11110/
