Andrew Bonney 29080ab4f6 Add support for apt package pinning
Adds variables to pin elastic package versions to ensure they
can't move out of sequence. An individual variable is added
for journalbeat given it is withdrawn from 7.16.

Includes a version bump to a more recent 7.x release which is
still compatible with this role
