By default, we have:
default_channels:
  - https://repo.anaconda.com/pkgs/main
  - https://repo.anaconda.com/pkgs/r

Set it to an empty list to make sure repo.anaconda.com
is not accessed (there shouldn't be any connection to it from the TN).

Using the conda_env module is more robust.
- If the handler failed for any reason, the env file had to be deleted
  for it to run again
- conda_env ensures the environment is up to date without having to recreate it

Using the conda module to update conda prevents to update from version
older than 4.6 (the module requires 4.6).
Using the command module should allow to update from older versions.

foo that isn't supposed to exist, does in conda-e3 for test

Avoid hard-coding /opt/conda

conda and conda_env share the same Conda class.
This class should be imported from another file but modules can only
use imports from ansible.module_utils due to the way the module is
copied to the host.

Avoid timeout on gitlab-runners

Need conda 4.6 already installed, so update the installer.

use_only_tar_bz2 is required for compatibility with Artifactory remote
conda repositories. Only .tar.bz2 are currently cached.

conda_default_env.sh is executed before conda.sh file and thus the conda
function is not known.
File renamed condaz_default_env.sh to be run after.

conda-e3 is now used to install pyepics and pvapy

Variable conda_default_env can be set to an environment name.
This environment will be automatically activated for all users (using
/etc/profile.d/conda_default_env.sh).

On the TN, we can't access repo.anaconda.com.
The channel_alias has to be set before trying to update conda.

Updated conda to 4.6.12

See merge request ics-ansible-galaxy/ics-ans-role-conda!1

Allow to specify the channels to use using the conda_channels variable.

The create and destroy playbooks are not required anymore.
They are part of molecule (for docker).

When installing conda with the installer, conda can be updated by using
conda. But when using the RPM, conda should only be updated with yum.

The RPMs provided by conda are currently updated very seldomly (conda
4.6.11 is available, but the only rpm available is still 4.5.12).
Using the installer gives better control of the version we want to
install.
