v1:
add 7 new cases using domain memory related API
add 1 conf for domain memory testing
v2:
fix the file not close problem and a typo
7 new cases are:
memory_params_config: test set memory params with config flag
memory_params_live: test set memory params with live flag
memory_peek: test memory peek
memory_stats: test get memory stats
set_maxmem_config: test set maximum memory with config flag
set_memory_config: test set current memory with config flag
set_memory_live: test set current memory with live flag
memory hotplug is not supported yet, so live set max memory case
is not added.
