Pass node to various Build*() functions

Pass node directly from XML to these functions

- BuildClusterImage()
- BuildImage()
- BuildProxy()
- BuildRunTests()

instead of reading the "server ID" and looking up from
eNB_IPAddress/eNB1_IPAddress/eNB2_IPAddress.

Improve the proxy build unit test by properly passing ctx information.
