[SPI] Investigate why OpenShift SPI doesn't work on OCP

[sleshchenko]

OpenShift SPI works fine on minishift instance with set user's credentials. But it doesn't work on OCP

In case of using a service account (with missing credentials) che-server doesn't have rights to create objects outside of its project.

In case of using user's credentials, there is another error

2017-10-05 15:34:59,923[nio-8080-exec-5]  [ERROR] [o.e.c.a.w.s.WorkspaceRuntimes 270]   - Unexpected response (401 Unauthorized), to the authorization request. Missing header:[Location]!

It is needed to investigate how we can provide OpenShift SPI rights to manage objects outside of its OpenShift Project.

So, deploy script for OCP flavor was broken this PR #6656 contains all required changes for deploying Che on OCP.

So, OpenShift spi doesn't work on Codenvy OCP instance (https://api.codenvy.openshift.com/) with set users' credentials(I guess it is because of keycloak server configuration to use LDAP authentication). It works somehow with service account but while #6284 is not resolved, starting workspaces in the same project doesn't work good enough.
Prepared PR also contains changes for setting oauth token instead of users' credentials for grant che-server permissions to create workspaces object outside of its OpenShift project.
