Implement execution environment handling

See merge request !74

Currently implements listing of remote and local docker
environments.

Add pillow to dependencies

See merge request !73

It was indirectly made available through beat/beat.core>

Remote experiment execution handling

Closes #62

See merge request !72

It provides a simple ncurses based cli GUI.

This allows to get the JSON data about the current
state of execution of an experiment.

As their name suggests, these commands will allow
to interact with the platform regarding the
execution of experiments.

Remove use of oset

The oset package triggers a warning with Python 3.7 that
if not fixed will make the package not working with
Python 3.8.

After some testing, the use of Python standard sets
seems to be enough for the needs of beat/beat.cmdline>.

Therefore remove oset.

See merge request !71

Update API v1 related code

See merge request !70

Following beat/beat.core> test prefix reorganisation,
the analyzer was moved under v1.

[doc] fixed external and internal links

See merge request !69

Fix non forkable types handling

See merge request !68

It will ensure it succeeds if the type can be forked and fail
otherwise.

The lists were wrong. All assets that can be versionned are not
forkable and experiment can currently be forked but has not version
support.

Update plotterparameter storage handling

Closes #61

See merge request !67

This gives better information when an error occurs during
the execution of a test.

Also pre-commit cleanup

This asset also has a storage therefore properly handle it.

Add support protocol template

See merge request !66

This allows for other tests to re-use these class methods
