- Add a new node `SRV6_ENCAP_NODE` to the CLI graph. This node allows
users to configure encapsulation parameters for SRv6, including the
source address of the outer encapsulating IPv6 header.
- Install a new CLI command `source-address` under the
`SRV6_ENCAP_NODE` node. This command is used to configure the source
address of the outer encapsulating IPv6 header.
- Install a new CLI command `no source-address` under the
`SRV6_ENCAP_NODE` node. This command is used to unset the
source address of the outer encapsulating IPv6 header and restore the
default source address.
Examples:
```
router# segment-routing
router(sr)# srv6
router(srv6)# encapsulation
router(srv6-encap)# source-address fc00:0:1::1
```
```
router# segment-routing
router(sr)# srv6
router(srv6)# encapsulation
router(srv6-encap)# no source-address
```

In this commit, we add two helper functions
`zebra_notify_srv6_locator_add` and `zebra_notify_srv6_locator_delete`.
These functions are used to notify locator additions/deletions to
zclients.

This commit is a part of #5853 works that add new ZAPI to
configure SRv6 locator which manages chunk prefix for
SRv6 SID IPv6 address for each routing protocol daemons.
NEW-ZAPIs:
* ZEBRA_SRV6_LOCATOR_ADD
* ZEBRA_SRV6_LOCATOR_DELETE
* ZEBRA_SRV6_MANAGER_CONNECT
* ZEBRA_SRV6_MANAGER_GET_LOCATOR_CHUNK
* ZEBRA_SRV6_MANAGER_RELEASE_LOCATOR_CHUNK
Zclient can connect to zebra's srv6-manager with
ZEBRA_SRV6_MANAGER_CONNECT api like a label-manager.
Then zclient uses ZEBRA_SRV6_MANAGER_GET_LOCATOR_CHUNK to
allocated dedicated locator chunk for it's routing protocol.
Zebra works for only prefix reservation and distribute
the ownership of the locator chunks for zcliens.
Then, zclient installs SRv6 function with
ZEBRA_ROUTE_ADD api with nh_seg6local_* fields.
This feature is already implemented by another PR(#7680).
