Support for infrastructure names defined by users

[tdviet]

Dear developers,

I would like to make a feature request: support for infrastructure names defined by users:

• At creation, users can specify short, unique names to their infrastructures. If no names are given at creation, IM may generate random, but human-readable names (like Docker does for containers), beside the UUIDs.
• The names will be added as prefix to the names of all resources related to the infrastructure: VMs, volumes, networks, security groups, ... at site level.
• The infrastructures can be accessible using the unique names (beside the UUIDs)

Enabling user-defined names beside UUIDs will improve user experiences, and greatly simplify resource management at site level, at it is clear from the first sight which resources belong to which infrastructure. Thank you.

This issue is related with grycap/im-dashboard#355.
Using the dashboard this functionality is partially implemented.

This issue is related with grycap/im-client#89
In the next im-client version, it will be supported.

In RADL and TOSCA, we have added the support to set a name (that may not be unique):
