[PROPOSAL] lock juju down to using charms from LTS and latest release only

Yes, support LTS(es) and leave current as experimental. I.e., the only
official charms are for LTS.
I'd actually like to go further and take all mention of series out of
the charm name and url. People care about services, not services wrt
series... it's noise for a large class of users.
Mixed-series environments work well (except on local)... I'll frequently
go to a known-good series/charm combo to mix into a stack no matter what
my default series is for that env.
I'd _ideally_ like to put any series-specific behavior into the charm
itself... perhaps extend metadata to include 'supported-series:'
(implying LTS releases only)... and most importantly, publish test
results for all our official charms against LTS(es). We should
additionally test those official charms against current/tip release for
charm development even though that's not an officially supported option.
