[jlandowner]

Close #744

• Remove Template Validation Webhook to be able to include default Templates in charts
• Remove URLBase from each Workspace Template
• Change controller-manager cli option(split --workspace-urlbase to --workspace-urlbase-domain, --workspace-urlbase-host and --workspace-urlbase-protocol)
• Change NetworkRule
  • add protocol and hostPrefix
  • remove name and host
• if hostPrefix is empty, portXXXX is used
• Change NetworkRule view
• only {{NETRULE}}, {{WORKSPACE}} and {{USER}} can be used in URLBaseHost
