[nebulous-gui] TC_19 TC_20 Registration of cloud provider

[Francisco Álvarez Terribas]

[summary]
Cannot validate manual installation of nebulous agent:

- There is no way to set roles to users, the system have the admin with all permisions and other manualy created users which seem to have restricted permisions. This is a precondition of TC_19 and TC_20.

Tests pass but precondition is not accomplished.

[environment]
Cluster installation: minikube start --memory=4g --driver=docker
Nebulous core manually installed following the wiki.
Added cloud provider (aws and openstack) following the wiki as admin user.

[steps to reproduce]
Add cloud provider following the wiki as admin user.

[expected results]
Pass test accomplishing preconditions.

[other relevant information]
The cloud provider is added to the list of cloud providers but the GUI doesn't give any meaningful feedback about the status of the cloud providers.
