The recent charm version is missing extra_packages, extra_pg_conf and local-monitor integration

[Bartosz Woronicz]

As in the title. The client have to redeploy the environment and cannot as some options dissapeared from the charm recently.

I understand that NRPE integration is phasing out but should be kept for now
- ['landscape-postgresql:local-monitors', 'nrpe:local-monitors']

But I don't understand the ability of configuring some option has dissapeared

  landscape-postgresql:
    bindings:
      ? ''
      : oam-space
    charm: postgresql
    num_units: 2
    options:
      extra_packages: python-apt postgresql-contrib postgresql-.*-debversion postgresql-plpython3-.*
      extra_pg_conf: 'max_connections=500
