[PATCH 01/10] docs: Document ability to configure lease time

[Michal Privoznik]

In v6.3.0-rc1~64 we've introduced ability to configure lease
time, but forgot to document the feature. Let's fix that.

Fixes: 97a0aa246799c97d0a9ca9ecd6b4fd932ae4756c
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1908631
