staticd: add support for SR Policies

Configuration example:

    ip route 9.9.9.9/32 6.6.6.6 color 123

The SR Policy to be chosen is uniquely identified by the policy
endpoint (6.6.6.6) and the SR-TE color (123). Traffic will be
augmented with an MPLS label stack according to the active
candidate path of that particular policy.

SR-TE Route Commands
====================
It is possible to specify a route using a SR-TE policy configured in Zebra.
e.g. to use the SR-TE policy with endpoint 6.6.6.6 and color 123 to reach the
network 9.9.9.9/24:
.. code-block:: frr
ip route 9.9.9.9/24 6.6.6.6 color 123
