Default channel to GA if not specified otherwise

[matejmatuska]

Originally we tried to map by default repositories from particular channels on the source system to their equivalents on the target system. IOW:

• eus -> eus
• aus -> aus
• e4s -> e4s
• "ga" -> "ga"
• ...

However, it has been revealed this logic should not apply on minor releases for which these non-ga (premium) repositories do not exist. So doing upgrade e.g. to 8.9, 8.10 , 9.3 for which specific eus, etc.. repositories are not defined lead to 404 error.

Discussing this deeply between stakeholders, it has been decided to drop this logic and target always to "ga" repositories unless the leapp is executed with instructions to choose a different channel (using envars, --channel .. option). To prevent this issue.

It's still possible to require mistakenly e.g. "eus" channel for the target release for which the related repositories are not defined. e.g.:

# leapp upgrade --channel eus --target 8.10

In such a case, the previous errors (404 Not found) can be hit again. But it will not happen by default. In this case, we expect and request people to understand what they want.

Thank you for contributing to the Leapp project!

Please note that every PR needs to comply with the Leapp Guidelines and must pass all tests in order to be mergeable.
If you want to request a review or rebuild a package in copr, you can use following commands as a comment:

• review please @oamg/developers to notify leapp developers of the review request
• /packit copr-build to submit a public copr build using packit

Packit will automatically schedule regression tests for this PR's build and latest upstream leapp build. If you need a different version of leapp, e.g. from PR#42, use /packit test oamg/leapp#42
Note that first time contributors cannot run tests automatically - they will be started by a reviewer.

It is possible to schedule specific on-demand tests as well. Currently 2 test sets are supported, beaker-minimal and kernel-rt, both can be used to be run on all upgrade paths or just a couple of specific ones.
To launch on-demand tests with packit:

• /packit test --labels kernel-rt to schedule kernel-rt tests set for all upgrade paths
• /packit test --labels beaker-minimal-8.10to9.4,kernel-rt-8.10to9.4 to schedule kernel-rt and beaker-minimal test sets for 8.10->9.4 upgrade path

See other labels for particular jobs defined in the .packit.yaml file.

Please open ticket in case you experience technical problem with the CI. (RH internal only)

Note: In case there are problems with tests not being triggered automatically on new PR/commit or pending for a long time, please contact leapp-infra.

The devel variable has precedence over both non-devel variable and CLI arg, as expected and also as documented in upstream docs.
