Acceptance tests validating security groups are indeed open

[gberche-orange]

• Given
  • A target service responding to HTTP on a given IP/port with a 200 status (IP1/port1)
  • A CF deployment with restricted security groups preventing acccess to IP1/port1
  • A service broker "SB1" that returns binding credentials of the form "http://IP1:port1/"
  • a sec-group-broker filter app is deployed, and filters SB1, and registered in the marketplace as service offering SO1
  • a service instance SI1 is created for service offering SO1 in space S1
  • an app A1 pushed from repo https://github.com/krujos/willitconnect exposed to route R1/v2/willitconnect
  • curl R1/v2/willitconnect -d '{"target":"http://IP1:port1/"}' returns "canConnect": false,
• When
  • SI1 is bound to A1
• Then
  • curl R1/v2/willitconnect -d '{"target":"http://IP1:port1/"}' returns "canConnect": true,
  • A security group is created in the space opening access to IP1:port1
