Merge branch 'evuez/gitlab-ce-webhook-url-spaces' into 'master'

Strip leading and trailing spaces in URL validator

_Originally opened at !2914 by @evuez._

It makes URLs in webhooks valid even if they contain leading and/or trailing spaces.

Spaces are hard to notice in input fields, this helps users by accepting leading and trailing spaces in webhooks URLs.

Fixes #13652

See merge request !2939
