[TODO_DPM] Some of the missing information from DPM APIs for the host

1) _get_cpu_info requires processor topology for the Host.

-> currently CPC_SOCKETS = 0 and CPC_THREADS = 1 are hardcoded which has to be updated with correct values.

-> features = list() is populated with empty list. Need to check if processor features can be populated here.

2) HYPERVISOR_VERSION = 1000 is hardcoded. What values from DPM can be used to determine the hypervisor version.

3) local_gb": 1024,"local_gb_used": 0, "disk_available_least": 1024 are some of the hardcoded values. Relevant mapping is to be done from values fetched on CPC

4) CPU up time on a partition:
