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

See merge request gitlab-org/gitlab-ee!3394

Introduce default usernames earlier

Closes gitlab-org/build/team-tasks#34

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.

CE Upstream - Monday

Closes gitlab-qa#99, gitaly#681, gitlab-qa#88 et gitlab-ce#31811

See merge request gitlab-org/gitlab-ee!3365

Upon reaching this step in the documentation we should have added 7
nodes to the consul environment; 3 servers, 4 clients, so update the
output to reflect that.

Additionally 10.1.2 uses the name `gitlab_consul` for its DC, so bring
that into line.

this test should be only testing for code that is in the

I also think that the coverage of this task is sufficient with
the CreateForkNetworkMembershipsRange tests.
