component/mca/buildout.cfg: Update mca release.

software/mca/software.cfg: Transfer the implementation to component/mca/

- Change set GOPATH to buildout's directory so that Go packages are sent to OBS.
- Switch back the default behavior to running Go tests and skip them in section golang1.17

- Re-enable $PYTHON_PATH variable in mca's Makefile
- Change the mca release.

- gitclone does not support download-cache, so it fails in OBS' servers.

Deactivate fluent-bit part as there is already a package with fluent-bit.
- A merge between the two packages can be made later on.

Explanations: The network tests are failing on OBS' VM for package building. This is a first fix which can be improved later.

Adjust paths.
Cleanup.

Use relative paths. Cleanup.

- Add metadata-collect-agent and its dependencies.
- Add fluent-bit output plugin for Wendelin (fluentbit_wendelin.so) and its dependencies.

CSR id shall be requested only when it's not available yet, as otherwise it
contacts caucase server needlessly, and in some circumstances it can result
with bogus new CSR.

Fixes a build error with recent gawk versions.

As refernce to the network-config-ipv4 part has been removed from the
publish-connection-information the part was not installed anymore, so the
netconfig.sh file was not added.

Fixed it by simply adding this part to the installed ones.

This fixes commit 3f7d8965
