Don't use f string yet

See merge request !116

The processing nodes are not on Python 3.6 yet
therefore these can not be used.

The other uses are only related to tests and
tasks not done on the processing nodes.

Only enable GPU runtime if available

See merge request !115

Some execution environments may run CPU as well as GPU
code, this check for Nvidia driver presence will allow
to reuse the same environment on both.

It also updates the GPU option to use the latest version
provided by the nvidia-docker2 documentation.

Improve execution handling

See merge request !114

This avoids accidental writes in the container that
will be lost anyway.

When starting a docker container, use the same user as the one
currently executing the code if nothing else has been put in
the configuration. This allows to have consistent access across
executions.

Add missing variable initialisation for optional argument in worker script

See merge request !113

Improve disconnection handling

See merge request !112

improve complex setup handling

Support giving a custom mount point to use for volume setup.

This will replace the cache path when creating the volumes.

Make cache access more specific

See merge request !110

It was not matching the one created by the original discovery
and thus fails to find the environments for the tests.

This will only mount what is needed by the various containers.

Improve handling of message handler shutdown in local executor

Handle docker exception following the raise on error property for the new environment discovery

Closes #93

See merge request !108

IF docker is installed or the daemon not accessible, the exception
propagation will not follow the raise on error property. This patch
fixes that and thus keeps the behaviour consistant.

Add logging information to lable based discover

See merge request !107

This will show information similar to the describe based
implementation.

Implement environment discovery using docker labels

See merge request !106

Samuel GAIST authored Jan 17, 2020 and Samuel GAIST committed Jan 17, 2020

The next release of BEAT environments will make use of docker
labels to provide the information the current describe command
returns (minus the os entry which is not currently used).

This new implementation of discovery uses these labels and thus
speeds up the process.

The original code is kept as a fallback method in case a node only
has images using the old build process.
