[LTP] [PATCH v7 2/4] ci: add patchwork communication script

[Andrea Cervesato <andrea.cervesato@suse.de>]

From: Andrea Cervesato <andrea.cervesato@suse.com>

Add a script to communicate with patchwork. Available commands are:

- state: change patch-series state
- check: send a tests report to patchwork
- verify: will print a list of new patch-series which has not been
  tested in the past hour (by default)

The script can be configured defining:

- PATCHWORK_URL: patchwork url to communicate with
- PATCHWORK_TOKEN: patchwork authentication token
- PATCHWORK_SINCE: timespan in seconds where we want to fetch
  patch-series
