Use localhost instead of che-host service name for checking KC

Make UserAuthValve and KeycloakUserChecker use localhost instead
of che-host for checkout keycloak tokens when CHE_API env var
is not set

This is a work around for the issue of che-host not being able to communicate with its own service on minishift 1.4.1 + OS 3.6. As an alternative, this comment worked for me.

I don't know what's the problem and if this is related but ... I still cannot access to che-server (the server is starting) with minishift 1.4.1 with this patch
I've got this at start up of the script openshift-deploy.sh

[CHE] Creating an OS route to debug Che wsmaster...error: [the provided version "apps.openshift.io/v1" has no relevant versions: group apps.openshift.io has not been registered, no matches for apps.openshift.io/, Kind=DeploymentConfig]
See 'oc expose -h' for help and examples.

when accessing to the che-server url from the browser, i've got

504 Gateway Time-out

The server didn't respond in time.

Though these error are gone with ifconfig docker0 promisc I have other issue when using the workspace ( got .error 403 on PUT from activity.js )

Maybe all my issue are related to keycloak + minishift 1.4.1
