PG HA: Rework headings to get unique links

Closes gitlab-org/build/team-tasks#30

See merge request gitlab-org/gitlab-ee!3419

As the flow of the PG HA documentation needs you to keep in mind several
roles, and visit them at multiple steps of the process, we end up with
mutiple headings called `Consul`, `PostgreSQL`, `Database`, and
`Pgbouncer`.

These headings become HTML anchors so a user can link to a particular
section of the document, but when needing to link to the Post-configure
of Consul you'd end up at the Consul section in user information.

Here we reword the headings.  They are less terse, but it allows for
deep-linking.

- Adds rescue clase to import_url method
- Ensure RemoteMirror model also validates the url

Closes #833

This option was undocumented and is not generally useful, and the code is
difficult to maintain.

Move merge service specs to EE module

See merge request gitlab-org/gitlab-ee!3383

POSTGRESQL_PASSWORD_HASH as with other postgresql password hashes, is
generated from md5(password + username).  The previous description
suggested it was just a hash of POSTGRESQL_USER_PASSWORD, which leads to
authentication failures

Closes https://gitlab.com/gitlab-org/build/team-tasks/issues/39

Specify which password should be used on Pgbouncer

Closes gitlab-org/build/team-tasks#37

See merge request gitlab-org/gitlab-ee!3400

It was a little unclear which password we should specify; it turns out
it's the pgbouncer password, which is used by consul to signal to the
pgbouncer service it should reload.

Fix docs to label file locking as EEP-only

Introduce default usernames earlier

See merge request gitlab-org/gitlab-ee!3398

Update the sample `consul members`

Closes gitlab-org/build/team-tasks#35

See merge request gitlab-org/gitlab-ee!3397

`CONSUL_USERNAME` and `PGBOUNCER_USERNAME` are used to derive
`CONSUL_PASSWORD_HASH` and `PGBOUNCER_PASSWORD_HASH`, so we should let
the user know their default values so we're not expecting them to jump
forward to the notes on the service.
