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.

The keytype field is actually `ssh-dss` for DSA keys and they will not
be stored as `id_rsa.pub`.
Note that newer version of ssh actually also support
`ecdsa-sha2-nistp256` and others so it is also misleading to assume the
field always starts with `ssh-`.
docs: raketasks: Add documentation on uploading to mounted shares
Fog has a local storage provider, which can be use to copy backups to locally mounted cifs / nfs / smb shares. This MR adds documentation to doc/raketasks/backup_restore.md in response to #3387.
@stanhu I found some time tonight and was able to get this started earlier than I initially expected, glad I could contribute.

Environment variables in the app
Fixes#3717 and #3519
## Why environment variables?
We need environmental variables, they are an expected way to configure apps https://medium.com/@kelseyhightower/12-fractured-apps-1080c73d481c#.ntrdiyu4c
This causes many tools and to tutorials to make it easy to set environmental variables and harder to supply a configuration file.
So even though we agree they are not ideal https://support.cloud.engineyard.com/hc/en-us/articles/205407508-Environment-Variables-and-Why-You-Shouldn-t-Use-Them the market has spoken.
## Why for GitLab the application and not for the Omnibus packages?
Environmental variables are also needed by people that do not run our Omnibus packages, for example natively bundled apps (Debian apt-get) and idiomatic Docker packages (Mesos, Kubernetes, etc.).
Of course it should work great with Omnibus packages too so any advise is welcome in that regard.
There is an MR https://gitlab.com/gitlab-org/omnibus-gitlab/merge_requests/575/diffs to be able to set any variable in gitlab.rb via environmental variables. I think both that and this MR should be merged to solve the configuration problem for both Omnibus and non-Omnibus installations. When both are merged the documentation should be crosslinked.
## Why uppercase?
Need to be all cap according to Google Shell guideline:
"Constants and Environment Variable Names => All caps, separated with underscores, declared at the top of the file."
https://google.github.io/styleguide/shell.xml#Constants_and_Environment_Variable_Names
Or as explained on http://stackoverflow.com/a/673940/613240
Keeping to this convention, you can rest assured that you don't need to know every environment variable used by UNIX tools or shells in order to avoid overwriting them. If it's your variable, lowercase it. If you export it, uppercase it.
