Adds JavaScript validation for group path editing

## What does this MR do?

- Prevents group_edit form submission when special characters are included in the new group name
- Enhances gl_field_errors to support this use case and be more re-usable. 

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

**The implementation of validation is here: https://gitlab.com/gitlab-org/gitlab-ce/commit/73d997046cac376ccdbcaac6f183002bc19b9a1f**

The rest of the diff for this MR is augmenting gl_field_errors

## Why was this MR needed?

- Currently we allow submission and a 500 error is returned.

Removes spaces in log messages.

refs:
- 6f7ccea6
- 7121a58e
- f54bf003

none of them seem to have added extra space deliberately (commit message is about something else)

## Why was this MR needed?

The spaces caused confusion when trying to analyze the logs, there was no space in user name, but log message indicated there was.

Replace links to the `Merge request description format` section with
up-to-date instructions on using the MR template built into the UI.

The `Merge request description format` section was removed in 2f7e28d1,
but links were left in the table of contents and in the MR description
instructions. Presumably, the section was removed because MR templates
are now provided by the GitLab UI.
