Implement matching of a machine to OpenShift container by pod annotations

[sleshchenko]

Description

Now dashboard matches a machine to OpenShift container only by composite machine name podName/containerName.
But in the scope of the following issue there is implemented another way that can be used.
It is needed to implement supporting of matching a machine to OpenShift container by Pod annotations.

So since API allows using the described naming approach Dashboard display wrong machines names.

Workspace config with the described naming approach

      "problems": [],

    }
  ],

}

typescript-ls and dev should be displayed as machines names but actually there are ws/typescript-ls and ws/dev.
