[dpdk-ci] [PATCH v2 02/10] tools: match by tree url instead of tree name

[<alialnu@oss.nvidia.com>]

From: Ali Alnubani <alialnu@nvidia.com>

The tree url has more information. It can be used to
get the maintainer of a tree, and it includes the tree name anyway.

Also try to use named capture groups as much as possible.
