feat: Add ansible-inventory credential support for save command

[fullstopdev]

• Create inventory_parser.go to parse ansible-inventory.yml
• Modify save command to load per-node/per-kind credentials
• Use dynamic approach: skip only non-network node kinds
• Credentials loaded in-memory, not persisted to topology
• Supports host-level and group-level credential fallback

Ansible inventory example:

nokia_srsim:
vars:
ansible_network_os: nokia.sros.md
# default connection type for nodes of this kind
# feel free to override this in your inventory
ansible_connection: ansible.netcommon.network_cli
ansible_user: admin
ansible_password: NokiaSrl1!
hosts:
dcgw1:
ansible_host: 172.80.80.51
dcgw2:
ansible_host: 172.80.80.52

can be tested with other username than admin which should have administrative rights:
[gl:/configure system security user-params local-user user "moussa"]
A:admin@dcgw1# info
password "$2y$10$S25cubWLYVEIafDa9Z.EU.sLWcsanISntEJcEqWSiIkw10qUojlpe"
access {
console true
netconf true
grpc true
}
console {
member ["administrative"]
}
