tests: Add initial support of CVM test on MSHV

Browse Source 
This patch adds the skeleton of the CVM test
support and modify existing scripts and test framework
to enable such scenario. Split the sha1sum to support both
regular and CVM guest. Add one test case for CVM. Will further
add more test cases.
