taking any parameter from a vm info file.

1) The pragma_boot in this script is now taking all parameters that a vm
info file provides. Note: the vm info file (test.vmconf) needs to have
"--" in all keys.
2) Shava added (probably during the PRAGMA26) that a cluster will be
removed when the corresponding condor job stops.
