Creation of a tenant in openvim providing a name is confusing

[gerardo-garcia]

When you run 'openvim tenant-create --name admin', openvim asks for the tenant name.

This is supposed to be correct, since the option --name overwrites the name provided in a file with the description of the tenant.
However, this is confusing for the end user.

Probably it would be practical to have an option for the name (without the need of a file) and another option for overwriting the name provided by the file.
