isisd: Add Segment Routing Local Block support
Segment Routing Local Block (SRLB) is part of RFC8667. This change introduces
the possibility for isisd to advertize SRLB in LSP. Base and Range of SRLB
could be configured through CLI or Yang.
Adjacency-SID are now using this SRLB for label allocation. SRLB could also
be used for SID-Binding (e.g. LDP to SR).
