Enhancement: Allow definition of redis & postgresql port

[Idly41]

Is your feature request related to a problem? Please describe.
Not really related to a problem, more a matter of principles :-).

As it seems, photonix uses the default ports for redis (6379) and postgres (5432).
In my infrastructure, I try to avoid static ports and use dynamic port assignments as much as possible.

Describe the solution you'd like
I would appreciate the ability to configure these ports via environment variables.

Describe alternatives you've considered
None really.

Additional context
Modern container based infrastructure are very dynamic and avoid static ports and IPs in order to allow the necessary flexibility (Kubernetes, Nomad, etc.)

Thanks @abmurksi - sounds important.

Not really important at the moment, but will be helpful in different deployment contexts.
And btw, many thanks for Photonix! It looks very well designed and shows a lot of promise!! I look forward to ride the journey with you :-)
