* LDAP: Allow an user to be synchronised against LDAP
This PR introduces the /ldap/sync/:id endpoint. It allows a user to be synchronized against LDAP on demand.

A few things to note are:

LDAP needs to be enabled for the sync to work
It only works against users that originally authenticated against LDAP
If the user is the Grafana admin and it needs to be disabled - it will not sync the information
Includes a tiny refactor that favours the JSONEq assertion helper instead of manually parsing JSON strings.

Adds a new requirements page to the installation docs.
Wanted/needed some place to document known browser 
issues and thought that adding this missing page together 
with OS, hardware, database and browser requirements 
would be a good thing.
Fix: move 6.4 section in upgrade notes further down.

Fixes #16487
