Add an enum value of EXCLUDE to the mpls-hop-type

[RyoheiFukui]

Change Scope

• Add an enum value of EXCLUDE to the mpls-hop-type under the mpls-te model
• This change is backwards compatible.

Users may specify the exclude address in explicit path specification for RSVP-TE LSP setup.

The configuration in Cisco shows the following

explicit-path name PATH1
 index 1 exclude-address ipv4 unicast 172.16.0.2

interface tunnel-te1
 destination 2.2.2.2
 path-option 10 explicit name PATH1
 path-option 20 dynamic

Given that several vendors' native YANG models are closely aligned with the description in EXRS (RFC4874 Sec.4.1)

Platform Implementations

• Implementation from Cicso: https://github.com/YangModels/yang/blob/main/vendor/cisco/xr/792/Cisco-IOS-XR-ip-iep-cfg.yang
• Implementation from Arista: https://www.arista.com/en/um-eos/eos-rsvp-te-commands#reference_vjp_cmq_w2c
• Implementation from DriveNets: DNOS CLI command

This seems ok from a model point of view. We will need at least one more vendor reference when you are ready before it can be approved.

FYI: I did find this Arista EOS command:
switch(config-te-rsvp-path-dyn-MyPath)# hop 10.0.56.6 exclude

@dplore
I added vendor implementation and corrected syntax errors. Could you execute /gcbrun?
