[Feature] | Allow admin to extend expiration of a user

[Chewbaka69]

Problem To Be Solved

When someone use an invitation with an expiration in 2 days, and you want to extend him for 2 more days or maybe 2 months.
Currently you need to wait that the user expired and re-send a invitation for 2 months etc.
Which is not really good for me

Suggested Solution

We can allow admin, to manually (and maybe by API) to extend the expiration of the user.
