When attempting to deploy to an OCP 3.x cluster the following error pops up:

Error creating: pods "nexus3-695b67564f-" is forbidden: unable to validate against any security context constraint: [fsGroup: Invalid value: []int64{200}: 200 is not an allowed group spec.containers[0].securityContext.securityContext.runAsUser: Invalid value: 200: must be in the ranges: [1000160000, 1000169999]]

As Nexus must run using this UID the cluster administrator needs to create a scc to work around this. It would be nice if we could supply this scc and have this documented.

The reason of this BUG is that OCP 3.11 has a default SCC that prevents userID with low numbers, such as 200 (the one Nexus uses). To fix this, a custom SCC must be created in the namespace. See: https://docs.openshift.com/container-platform/3.11/install_config/persistent_storage/pod_security_context.html

We will document and add a SCC example to the project to help administrators have the operator working on OCP 3.11 clusters.

Pushing to 0.2.0, if we have the time by the end of the milestone we should include this one.

Make Deployments use the ServiceAccount informed in
`nexus.spec.serviceAccountName`. If none is informed the default SA
created by the operator-sdk in `deploy/`is used. Assumes the default
account has not been deleted, the Deployment will trigger an event
otherwise.

Fix m88i#41 by adding SCCs which can be used by the cluster admin and
documenting their use.
