Add missing delete method in mattermost session

See merge request gitlab-org/gitlab-ce!16209

This was causing user deletions to time out.

Closes #44008

API requests were timing out because `tag_id` was missing an index. These
migrations were imported by running https://github.com/mbleigh/acts-as-taggable-on#post-installation:

```
bundle exec rake acts_as_taggable_on_engine:install:migrations
```

It looks like the `acts-as-tagglable` gem added the indexes in v4.0.0, but
when we upgraded from v3.5.0 (back in 2016 via
f571aeb5) we did not add them.

On staging, there are about 10.7 million rows on the `taggings` table. It took about 30 seconds for each index to be created.

On production, there are about 17.4 million rows, so I suspect the time to be about a minute per index.

Removes confusing/unnecessary checkboxes when trying to configure an
integration. If there is only one supported event we don't need to
allow these to be individually disabled since the integration can be
disabled instead.

E.g. Project Integrations for GitHub, Bugzilla, Asana, Pipeline emails and Gemnasium

Allows integrations to override which triggers are configurable
