Add --paste-global-conf option

[moriyoshi]

While bootstraping gunicorn with paster (PasteScript) or pserve (Pyramid) is now discouraged, no options are provided for PasteDeploy users to set global configuration variables from the commandline.

This patch adds the new commandline option --paste-global-conf KEY=VALUE so that the users can pass arbitrary global_conf values to the PasteDeploy entrypoint.

The regular expression here is a raw string, so should there be only one backslash?

[tilgovi]

Ignore me. Right. The backslash here is not for character escape but for regular expression escape. Whole reason for the raw is to not have \\\\.

LGTM

Maybe we should add to the docstring that it can be specified multiple times? Also, I wonder if --paste-global is better than --paste-global-conf. When I see the -conf suffix I think of a full configuration, like if it were parsed as JSON syntax or something. Maybe that is just me. How about --paste-var to make it very explicit that it's a single variable?

• Adding docstring

  Makes sense to me.

• Changing --paste-global-conf to --paste-global or --paste-var

  Also sounds reasonable. For me --paste-global looks better because there is a concept of "local configuration" and --paste-var would be a bit confusing.

Thanks!
