Patch to add key-int-max

Adds key-int-max property to gstreamer element

Tested with without property to make sure default element behaviour doesnt
change.

Also tested with


gst-launch-1.0 -v videotestsrc is-live=true ! x265enc tune=4 key-int-max=5 !
fakesink silent=false

And confirmed we get keyframes every 5 frames.
