* docs: add description of init container image definition

Co-authored-by: kurokobo <kuro664@gmail.com>

fix: correct readinesProbe for web pod

* add noxfile with mkdocs build session

* add nox build check

* include reusable nox in ci workflow

With ansible 2.9.27 (operator-sdk v1.27.0) then the reverse filter
returns an iterator so we need to cast it to list.
The behavior doesn't exist when using a more recent operator-sdk
version like v1.34.0 (ansible-core 2.15.8) but using the list
filter on that version works too (even if not needed)

* in the sclorg Postgresql 15 image, the PGDATA directory is hardcoded
* if users were to modify this directory, they would only change the
  directory the pvc is mounted to, not the directory PostgreSQL uses.
  This would result in loss of data.
* switch from /var/lib/pgsql/data/pgdata to /var/lib/pgsql/data/userdata

Fix "external_hostname" required on OCP

…yments (#1805)

Add postgres init container if
postgres_data_volume_init is true

This is aimed to solve the issue where users may
need to chmod or chown the postgres
data volume for user 26, which is the user
that is running postgres in the sclorg image.

For example, one can now set the follow on the AWX spec:
spec:
  postgres_init_container_commands: |
    chown 26:0 /var/lib/pgsql/data
    chmod 700 /var/lib/pgsql/data

Deprecate postgres_init_container_resource_requirements param in favor
of postgres_resource_requirements param.
