Allow to schedule tentacle upgrade
We have lot of tentacles, a nice feature could be to schedule the tentacles update (date and time). Select the time and date to upgrade the tentacles automatically (normally at night with low server activity)
Noticed today after upgrading from 2018.4 to 2018.6, that the tentacle upgrades hindered deployment while the upgrade task was running. In many cases it's more important to upgrade the server itself for ui fixes and such, but having to due halt all deployment for a couple of hours due to health checks and upgrades afterwards makes updates really annoying to do during work hours.
If the tentacle upgrade task could be scheduled to a custom time, such as night time, updates would be easier to manage during work hours.
