remove unnecessary chmod

[Documentation] simplify 6.0 to 7.2 upgrade guide

`lib/support/init.d/gitlab` was set as executable in the repo as of the
6.1 release so chmod is not needed after that. See
https://github.com/gitlabhq/gitlabhq/pull/7586/files#r16885445.

API: Filter issues by state

While working on [laboard](https://gitlab.com/jubianchi/laboard) I had some issues with the API : I was not able to filter issues by state so I had to write some logic to do it on my side.

I think it will be useful to have this feature supported by the Gitlab API, moreover, the MR API already provides such filter capabilities.

I added the filtering logic on `/issues` and `/projects/:id/issues`.

The commits are not squashed but I'll do it once everything seems ok to you.
