[Libvirt-cim] [PATCH 0 of 2] #2 Remove devid-style InstanceID support from ELEC and EC.

[Kaitlin Rupert]

Removed devid-style InstanceID support from ELEC - this class now uses just the name of domain.

This caused a needed update in EC - cap_to_cs() no longer needs to parse devid-style InstanceIDs.

Updates:  None
This is acutally just a resend.  Heidi suggested to add connect_by_classname() to return_vsm_cap() in VSMC.  However, since this patchset doesn't address changes in VSMC, I'll be sending the VSMC change as a seperate patch.
