ironicclient can not create node with uppercase characters in name

[Kyrylo Romanenko]

Ironic client can not create node with name containing uppercase symbols

Steps:

1. SSH to controller node, source openrc.
2. Try to create node with uppercase in name:

root@node-1:~# ironic node-create -d fuel_ssh --name NODE
Cannot create node with invalid name Node (HTTP 400)
root@node-1:~# ironic node-create -d fuel_ssh --name Node
Cannot create node with invalid name Node (HTTP 400)
root@node-1:~# ironic node-create -d fuel_ssh --name somethingnamE
Cannot create node with invalid name somethingnamE (HTTP 400)

Expected to create node with name regardless to uppercase or lowercase.

looks like a known bug/limitation [1], and fixed in upstream [2] in LIberty release.

Before node name had to comply with internet FQDN hostname, now node name needs to comply with RFC3986 [3]
