Do not call API if there is no API URL

Fixes #5878 

CE users may not be interested in the new JIRA features. In this case,
we should detect they haven't set an API URL and fallback to the
behavior pre-8.3. This patch does that very easily.

There are planned improvements to JIRA in future releases such as
gitlab-org/gitlab-ce#5541 which will make this more configurable.

Suppress e-mails on failed builds if allow_failure is set

Every time I push to GitLab, I get > 2 emails saying a spec failed when I don't care about the benchmarks and others that have `allow_failure` set to `true`.

@ayufan mentioned creating a summary e-mail to prevent getting one e-mail per build, but the latter might actually be desirable. For example, I do want to know if Rubocop errors fail right away.

Project services and JIRA documentation clean up

Closes https://gitlab.com/gitlab-org/gitlab-ee/issues/176

This was first aiming to fix the JIRA references to EE, but as I was going through it, I decided to revamp more.

@Haydn once merged here and then Valery merges CE into EE it should be fixed in doc.gitlab.com as well.

@dblessing the docs state that we support JIRA 6.x. I see that 7.x is out, should the docs be amended? Also we seem to have a place to document services (http://doc.gitlab.com/ce/project_services/project_services.html), but the JIRA doc is under integration :/ I'd like it to have it moved under `project_services/`, but I guess most customers know the current URL better.

Delete tag via API

### What does this MR do?

Implements deleting a tag via the API.

### Are there points in the code the reviewer needs to double check?

On success, it returns the name of the deleted tag. This is similar to the [delete branch API](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/lib/api/branches.rb#L111).

###  What are the relevant issue numbers / Feature requests?

* This MR closes #1575 
* Closes http://feedback.gitlab.com/forums/176466-general/suggestions/6599203-delete-tags-through-the-api

@stanhu Could you do a review?

of a database not existing, instead of raising an error.
