Add licenses api parameters and fix a missing variable in license view.

[ncareau]

Description

Added 2 parameters in the license API in order to filter maintained licenses and licenses that expires or not.

Also added a missing item that wasn't shown in the license view, the maintained field was not displayed.

I didn't find where i could change the API documentation in the repo. If you could point me in the right direction i'll make the necessary changes (add both expires and maintained parameters.)

As mentionned in #9834, this PR is for the develop branch. I made changed to develop-v6-integration in #9890.

We should probably use the localization strings here instead of hard-coding Yes/No. I believe you can find them as general.yes and general.no

I'll fix it - no worries :)
