THREESCALE-8749: Ability to set APICAST_SERVICE_CACHE_SIZE

[sergioifg94]

Description

Add optional field in the Apicast resource that sets the APICAST_SERVICE_CACHE_SIZE environment variable in the Apicast container

Verification steps

On a cluster, run the operator and create an APICast with the new field set. Check that once reconciled the Deployment includes the environment variable with the value from the new fields:

1. Apply the manifests

   make install

2. Run the operator

   make run

3. Create an APICast that includes the following in the spec:

   spec:
     // ...   
     serviceCacheSize: 42

4. Check the Deployment for APICast

   oc get deployment/apicast-example-apicast -o yaml

5. Verify that they include the environment variable

   # ...
   - name: APICAST_SERVICE_CACHE_SIZE
      value: '42'
   # ...

Looking good.

Needs doc, at least in the APIcast CRD ref https://github.com/3scale/apicast-operator/blob/master/doc/apicast-crd-reference.md
