Since yesterday, software/gitlab can no longer be installed with an
error while installing gitlab_npm:

    ERR! Invalid dependency type requested: alias

This is because we are using npm install to install a repository which
uses yarn.lock to pin versions, so the install was done without having
the dependencies pinned. Using an old yarn for this repository does not
seem so easy, so we just have made a commit to convert the yarn.lock to
a package-lock.json, so that we don't have to update the tooling here.

Once we update, we'll rework this part of the software to use yarn, it
seems gitlab still uses yarn in more recent versions.

`git describe` also produced different (more correct) output, because
some tags were missing in our mirror of gitlab-ce.

We can use mathematical relation in between ports, channels and tx/rx endpoints
to bring structure and clarity in RU setup.

Also, while on it, document how tx/rx data flow are organized as it was not
clear just from reading ORAN specs and I had to deduce it.

Our python interpreter uses ncclient which depends on lxml egg, but does not
explicitly specify to use that lxml from slapos component.

Until now we were lucky because slapos-cookbook depends on the correct lxml and
we have slapos-cookbook as the second entry in the part list with only
`template` preceding it.

However I needed to use pythonwitheggs inside that template and then got the
build failure, because now pythonwitheggs was built before slapos-cookbook and
tried to use lxml without slapos component:

    INFO Building without Cython.
    INFO Error: Please make sure the libxml2 and libxslt development packages are installed.
    INFO An error occurred when trying to install lxml 4.9.1. Look above this message for any errors that were output by easy_install.

-> Fix it by explicitly specifying in-slapos lxml egg to be used.

Bring more structure to RU-specific code as a preparatory step for multiRU support:

- move RU-specific files under ru/<RU-type>/ . This mostly moves Lopcomm programs and configuration files there.
- move RU-specific instance code there as well. This also mostly moves Lopcomm specific services and promises there.
- bring more structure in naming. As buildout has global namespace use ru_<RU-type>_ prefix to avoid collision in names.

This should be a preparatory patch with practically no semantic change, but
preparing ground for further multiRU landing.
