CLOUDSTACK-7958: Add configuration for limit to CIDRs for Admin API calls
The global setting 'management.admin.cidr' is set to 0.0.0.0/0,::/0
by default preserve the current behavior and thus allow API calls
for Admin accounts from all IPv4 and IPv6 subnets.
Users can set it to a comma-separated list of IPv4/IPv6 subnets to
restrict API calls for Admin accounts to certain parts of their network(s).
This is to improve Security. Should a attacker steal the Access/Secret key
of a Admin account he/she still needs to be in a subnet from where Admin
accounts
are allowed to perform API calls.
This is a good security measure for APIs which are connected to the public
internet.
This PR also includes a commit to cleanup and improve NetUtils.
No existing methods have been altered. That has been verified by adding
additional Unit Tests for this.

Cleanup and Improve NetUtils
This class had many unused methods, inconsistent names and redundant code.
This commit cleans up code, renames a few methods and constants.
Methods were renamed to clearly show that they are for IPv4 or IPv6.
Tests were improved and added to test the changes that were made to the
code.
