What is this change about?

Currently the Dynamic ASG test works the following way:

• Make a request from a test app to cloud-controller-ng.service.cf.internal:9024/v2/info
• Verify the request was blocked
• Add a security group rule allows the app to make TCP connections to port 9024 in IP range 10.0.0.0/8
• Verify the request is now allowed
• Remove the security group
• Verify the request is blocked again

This test requires/assumes that:

• cloud-controller-ng.service.cf.internal:9024 is currently blocked by the platform-wide running ASGs
• The Cloud Controller is deployed to an IP in the range 10.0.0.0/8
• cloud-controller-ng.service.cf.internal resolves to a Cloud Controller VM IP

This PR adds an optional configuration parameter dynamic_asg_test_config which can be used to change the test to work in environments where the above assumptions don't hold. By default the test will use the current logic, but dynamic_asg_test_config can be used to override the following parameters:

• endpoint_host: Hostname or IP for test endpoint to allow/block
• endpoint_port: Port for test endpoint to allow/block
• endpoint_path: HTTP Path for test endpoint to allow/block
• endpoint_allow_ip_range: IP range used for allowing and blocking access to the test endpoint. This can be a single IP address, a range like 192.0.2.0-192.0.2.50, or a CIDR block like 10.0.0.0/8.
