fix for pymongo performance too slow
Changes:
Bugfix: Added automatic detection for installations where pymongo does not have
the appropriate C extensions (the absence of these can cause a 20x slowndown).
A very conspicuous (and annoying) warning is printed out *every time* the
mongodb datastore adapter is called, pratically forcing the user to re-install
pymongo with the appropriate extensions.
Bugfix: The script "cb_create_gmetad_config_file.sh" (on "common") still had
the directory "cloudbench" hard-coded on it.
added base specweb scripts without specweb jars

Add basic vCloud Director cloud library; add SNMP polling as a check-boot-complete polling method
Small fix for Daniel's code (snmp polling): just moved the snmp import
to the internal part of the if in the shared_functions.py file. It
ensures that older installations (and VMs) continues to work, even
without the snmp-python dependency installed.
