Filter security group list on the ID's we expect

Browse Source 
Filter the list of security groups based on the security
group IDs we plan on using for the network. Also only
get the id field as this is all we need to compare.

Fixes an issue where deployment fail on systems with a
high number of security groups.

Fixes an issue where baremetal node deployment would fail on clouds
with a high number of security groups. Listing the security groups
took too long. Instead of listing all security groups, a query filter
was added to list only the security groups to be used for the network.
