Description

We can consolidate the current content in
https://yunikorn.apache.org/community/sessions/ and rebuild it with the
following sections:

Coming Meetup session
 - speaker
 - abstract
 - date and time

Past sessions, conf talks
  - a list of past session recordings

And then add a section somewhere in the homepage for the "upcoming meetup".
