swrap should start ssh-agent only if it is not running, or stop it after completion.

see the gist

Starting ned jobs running in the same container need to take care of:

• proper bindings, have to filter SINGULARITY_BIND and exclude /tmp and other non-shared directories
  possibly take care of new agent directories etc.
• propper passing of env variables

1. Now on claster charon test end with error:
   INFO: Using cached SIF image
   Host key verification failed.
   =>> PBS: job killed: walltime 1241 exceeded limit 1200

Proposed start of ssh-agent for local passphrases in .bashrc:

env=~/.ssh/agent.env

agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; }

agent_start () {
    (umask 077; ssh-agent >| "$env")
    . "$env" >| /dev/null ; }

• study meaning of agent.env
• review initialization of the ssh-agent, at least we should check that it is already running

Python implementation still depends on the Python. Moreover if we want to separate it to more modules it must probably be installed. That could make problems if pip and/or venv is not available. To this end we propose:

1. use only standard Python packages
2. Do not use setuptools, make main bash scripts that calls python with modified PYTHONPATH.
3. For stable pieces of the code reimplement it in pure bash/sh.
