Include/Exclude filters do not split comma-separated values

@xeniape found this bug

Affected version

25.3.0

Current and expected behavior

Current Behaviour:

stackablectl release install 25.3 -e airflow,druid

This installs all operators. None are excluded, because there is no operator named airflow,druid.

Expected behaviour:

The help text suggest you can specify multiple values (INCLUDED_PRODUCTS and EXCLUDED_PRODUCTS):

Options:
  -i, --include <INCLUDED_PRODUCTS>
          Whitelist of product operators to install

  -e, --exclude <EXCLUDED_PRODUCTS>
          Blacklist of product operators to install

stackablectl release install 25.3 -e airflow,druid

This should install all operators for the release, except airflow and druid.

Possible solution

Try to unmarshall the comma-separated list of operators (or at least error out).

Comienza con el comando stackablectl release install y sigue cómo se analizan las opciones --include y --exclude. Reproduce el problema con stackablectl release install 25.3 -e airflow,druid; se considera hecho cuando los valores separados por comas excluyen ambos operadores o el comando informa claramente de que el valor no es válido.
