Provide a CLI command to generate/update docker files

[cescoffier]

Description

When a user wants to use a dockerfile, instead of generating one during the project generation, let's provide a one-off command that generates and update dockerfiles.

It should be able to generate (depending on the user choice):

• JVM container
• Native container using quarkus micro
• Native container using ubi minimum
• Native container using quarkus distroless

Once generated, the quarkus container build should default to these generated dockerfiles.

[quarkus-bot[bot]]

/cc @ebullient (cli), @maxandersen (cli)

[maxandersen]

this seems like duplicate or subpart of #24502 ?

[maxandersen]

btw. by update are you thinking something more than regenerating ? (i.e. not intended to keep users own edits)

[ia3andy]

for the update I think he means keeping up to date.

I am willing to tackle this, when I am done with the udpate tool stuff if that makes sense @maxandersen (I would like the RHTAP story to be perfect with Quarkus)
