Ability for the client to sync configuration in real time

Now the client needs to be update manually (new token generated manually, then manually instance needs to be updated in the client).
We need a quasi real time and automatic updates for the client.

Huge +1 for this, it is the big thing I'm missing as we often add allowed IPs and are looking for a way to keep client configs in sync.

@wojcik91 counting that the activation and sync process of client - as it also has enrollment in it - will fix as well: #703
