What changes:
Write the disk and partition usage information to the STATE_DB in redis
The physical memory stats will also be in the same MIB OID

How:
Modify procdockerstatsd to routinely update the redis table

How to verify:
STATE_DB will contain updated "MOUNT_POINTS" entries for the disk usage and "MEMORY_STATS" for physical memory stats
Unit tests added to verify correctness
Coverage tests also added

Description for changelog:
