Fix create call for security group rules

We need to fix the create security group call to
correctly use the per-datastore configs to set the
port, and protocol values for the security group rule.

The only parameter that the trove user should be able to
specify for the rule is the CIDR.

Changes:
- Use the datastore specific ports and protocol for creating
  the new security group rule.

Changes:
- using datastore-specific ports for building new rules, based upon income CIDR;
