Sanitization of job name and tests for PBS

[gpetretto]

To address this issue Matgenix/jobflow-remote#112 introduce a sanitization for the name of the jobs for PBS and SGE. The choice of the characters to replace is based on explicit tests in the PBS and SGE containers from jobflow-remote's integration tests.

Also adding test for PBS as some regression was introduced when adding SGE. It would be better to add integration tests similar to jobflow-remote to improve the reliability.

A few notes:

• The separator for the job ids in the list of jobs command works differently for PBS and SGE. A comma for SGE and a space for PBS. Tests will need to be adapted. Waiting for updates from fix parse_jobs_list_output parsing issues with SGE #52
• It seems that in OpenPBS the -f format option is ignored when filtering by username with the -u option:

  $ qstat -u jobflow -f
  
  4250a605a812:
                                                              Req'd  Req'd   Elap
  Job ID          Username Queue    Jobname    SessID NDS TSK Memory Time  S Time
  --------------- -------- -------- ---------- ------ --- --- ------ ----- - -----
  2003.4250a605a* jobflow  workq    myscript      958   1   1    --  01:00 R 00:00
  

  Does this work for PBSpro or other PBS versions? Should we cover this case for OpenPBS?

Few updates following the merge of #52.

Concerning the query based on users, it seems that qstat shows the same format when filter by user and job_id if adding the -w. I tested this in the OpenPBS based container and it seems to work correctly.

Almost all good to me. I think there is one small bug in the data_objects (see comment). Then a few comments here and there. Otherwise great work!
