Allow dots in group names to pass validation for Create Group and Edit Group forms

## What does this MR do?
Allows dots within group names to pass form validation when creating or editing a group.

## Are there points in the code the reviewer needs to double check?
Nope, pretty straight forward.

## Why was this MR needed?
Although group names with dots are allowed, our frontend validation mistakenly invalidates them

Make test suite deterministic when storage is involved

## What does this MR do?

This MR fixes our RSpec test harness because one test example could affect subsequent examples if objects created with `let` had associated files stored in `tmp/tests`.

We store files using CarrierWave, but we also have some custom storage rules for CI builds. Some time ago we introduced MR that purged CarrierWave uploads after each run of entire test suite https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3435, but this is not enough, as we should isolate each test example to be able to rely on deterministic test suite.

Not cleaning uploads between each test example run, makes it impossible to know if preconditions are correct before test example starts to run, therefore it makes test examples, that use storage, unreliable. This MR is an attempt to improve that.

Fixed issue boards scrolling with a lot of lists & issues

## What does this MR do?

When an issue board has a lot of lists & each list has a lot of issues scrolling can be tricky. This changes that by making the element that scrolls the `board-list` div. This is ok because sorting inside each list isn't possible, it will need re-thinking when sorting is possible but this fixes the bug for now.

Stop supporting Google Cloud and Azure as backup strategies

## What does this MR do?

It removes support for Azure and Google Cloud as backup strategies (via Fog).

Motivation behind this decision can be found in !4928, !6713 but basically they require a lot of gems that are unrelated to the backup use-case.

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

Am I missing any other location where we'd use these gems?

Fixed issue boards issue sorting when dragging issue into list

## What does this MR do?

Currently it just appends the new issue to the end of list & then sorts by priority which can cause some strange effects. For example if you drag the issue to the top of the list & then vue re-renders, the issue actually goes to the bottom.

This changes that by adding the issue at the specific index.

## Screenshots (if relevant)

See merge request !7734

When a board has a lot of lists & issues scrolling stops the user from moving the issue to the lsat list (or any list not on screen). This changes that by making the scrollable element the board-list element. This will need re-thinking when sorting in lists is possible.
