Implement builder for python

New builder feature activated by

`ops ide deploy` and `ops ide devel`

If there is a requirements.txt at the top level (later pom.xml, package.jsom go.mod and so on):

hash the requirements.txt
build if not already built an image
:

It should be rebuild only if the hash chnages

See the code here (a protype)
https://github.com/mastrogpt/olaris-a41/blob/b7e9f4ad00b3e9043fefcbac880552280d8a5710/opsfile.yml#L108

The deploy when parsing parameters should check `--docker auto` it should replace with --docker python

Note crate a .ops/image.python with the hash
use it to save the hash
