Place holder class to provide convenience for testing, modifying, and retrieving Eucalyptus cloud property information
Intention is to reduce the time in looking up property names, and values outside of the eutester test lib, etc
Note: Debug output for the tester.sys command are controled by the eutester/eucaops object
Sample:
props = EucaProperties(myeutesterobject)
#get some property values
mysanhost = props.get_storage_sanhost()[0]
mysanhostp1 = props.get_storage_sanhost(zone='PARTI01')[0]
#use a convenience method to set a property
prop.set_storage_sanhost('192.168.1.1',zone='PARTI01')
#get the property string value for a given property
sanhostp1propertystring = props.get_storage_sanhost(zone=PARTI01)[1]
#reset a cloud property to it's default value
props.reset_property_to_default(sanhostp1propertystring)
