developer user needs access to internal registry

[jodyhuntatx]

To push images to the Openshift repo, the system:admin needs to grant access to the developer user. That's not in the deployment scripts. I wrote this, should probably go in the 1_create_conjur_namespace.sh script.
This may grant excessive privileges so some scrutiny/testing is warranted.

$ cat grant-user-access.sh
#!/bin/bash
if [[ $# -ne 1 ]]; then
echo "Provide name of developer user..."
exit -1
fi
USER=$1
oc adm policy add-role-to-user system:registry $USER
oc adm policy add-role-to-user system:image-builder $USER

oc adm policy add-role-to-user admin developer -n default
oc adm policy add-role-to-user admin developer -n $CONJUR_NAMESPACE_NAME
