Hardware information on flavours

[enolfc]

Short Description of the issue

Ideally, the flavours description should include some information about the underlying hardware:

• type of CPU
• overcommitment (if any)
• type of disk (e.g. SSD)
• type of network

while some of this is already provided, other info not.

Should check what is realistic to provide in an automated way and how to add the information to the Glue Schema.
