[dpdk-ci] [PATCH v3 09/10] tools: filter new patchwork IDs by project name

[Ali Alnubani]

If the script doesn't filter by project, it would be fetching patches
from all projects, which we don't want as different projects
require different checks usually. This patch modifies the script so
that it requires a project's name to fetch IDs for.

Example usage:
$ export MAINTAINERS_FILE_PATH=/path/to/dpdk/MAINTAINERS
$ ./tools/poll-pw series DPDK /path/to/last.txt \
    '/path/to/pw_maintainers_cli.py --type series set_pw_delegate $1'

Changes in v3:
- Filter by project using jq, since the events API doesn't have a
  'project' parameter.
- Redirect error messages to stderr.
