[__jitsi_meet] Adapt jicofo and videobridge memory usage

This enables us to setup smaller jitsi instances that work reliably.

We set 3 threshholds:
- < 3G RAM: use 0.75G max memory
- < 5G RAM: use 1G max memory
- < 8G RAM: use 2G max memory
- >= 8G RAM: use 3G max memory (jitsi's default)

For more information as to why and how this is done, see:

as investigated back in the day by @pedro

Alternatively, you can help finance that work; get in touch with the type
authors for that (see below).
This type takes care of adapting the maximum memory used by jicofo and
videobridge in function of the hosts installed memory.
NOTE: This type currently does not deal with setting up coturn.
For that, you might want to check `__coturn` in
