Cpu Manager - make CoreID's platform unique

**What this PR does / why we need it**:
Cpu Manager uses topology from cAdvisor(`/proc/cpuinfo`) where coreID's are socket unique - not platform unique - this causes problems on multi-socket platforms.

All code assumes unique coreID's (on platform) -  `Discovery` function has been changed to assign CoreID as the lowest cpuID from all cpus belonging to the same core. This can be expressed as:
`CoreID=min(cpuID's on the same core)`

Since cpuID's are platform unique - above gives us guarantee that CoreID's will also be platform unique.
