Description of problem:

When a Re-Encrypt Termination route is created the ca-file not created in /var/lib/containers/router/cacerts/<PROJECT><ROUTE_NAME>  when created with only destinationCACertificate, cert and key are not included due to wanting to use the routers "--default-cert"


Version-Release number of selected component (if applicable):
3.1.1.6

How reproducible:
100%

Steps to Reproduce:
1. Create route [1] 

2. `oc rsh router` 

3. $ grep bug haproxy.config                  
    backend be_secure_default_bug-reencrypt
    cookie OPENSHIFT_REENCRYPT_default_bug-reencrypt_SERVERID insert indirect nocache httponly secure
    server 10.1.5.18:5000 10.1.5.18:5000 ssl check inter 5000ms verify required ca-file /var/lib/containers/router/cacerts/default_bug-reencrypt.pem cookie 10.1.5.18:5000

4.ll /var/lib/containers/router/cacerts/ -a
  total 8
  drwxrwxrwx. 2 root root   37 Mar 10 14:33 .
  drwxrwxrwx. 4 root root   50 Mar  9 10:29 ..
  -rw-r--r--. 1 root root 4109 Mar 10 14:33 default_test-secured.pem


Actual results:


  [ALERT] 056/103231 (25235) : Proxy 'default_bug-reencrypt', server '10.1.0.66:8443' [/var/lib/haproxy/conf/haproxy.config:302] unable to load CA file '/var/lib/containers/router/cacerts/default_bug-reencrypt.pem'.
  [ALERT] 056/103231 (25235) : Fatal errors found in configuration.


Expected results:

Work with the default certs and the supplied destinationCACertificate for a Re-Encrypt Termination route
