## Problem

The split between `agama config` and `agama profile` commands is
arbitrary, and the subcommands are not very consistent.

## Solution

Following a discussion:
- `agama profile import` is replaced by `agama config generate | agama
config load`
- `agama profile evaluate` and `agama profile autoyast` are replaced by
`agama config generate`
- `agama profile validate` renamed to `agama config validate`

More consistency in stdio handling, adding `--output` option

- [x] update `agama-auto`

Review suggestion:
- `service/test/integration/profile_itest.rb` is an integration test,
supposed to be human readable. Please suggest improvements both in
domain coverage and test readabililty. See
`service/test/integration/README.md` on how to run it

## Testing

- `service/test/integration/profile_itest.rb` extended
- manual test of `inst.auto=http://.../config.jsonnet` and `inst.auto=`
finding it on `OEMDRV` (see [a
gist](https://gist.github.com/mvidner/d377768d54ae0ba39cd1e62672eec99a)
for setup)
