[jira] [Commented] (METRON-411) Support Greater Range of Profile
Periods

METRON-411 Support Greater Range of Profile Periods
Depends on existing pull requests #236 #237 and #242 . The diff might look a little wonky until those other PRs are merged.
### Problem
The current Profiler's deterministic row key design limits the range of profile period durations available to a user. The original goal was to support 15 minute periods which it does, along with 5, 20, 30 and 60 minute periods. Different types of profiles and input data will require a range of periods and the Profiler should be flexible in this regard.
Currently, a profile period must start on each and every hour. While 1, 2, 3, 4, 6, or 240 periods per hour is acceptable, 5 periods per hour is not. The number of periods per hour must be either a multiple or divisor of 60. Also, a period cannot be any longer than an hour. In some cases 2, 4, or 8 hour periods might be useful.
### Solution
This change uses a much simpler method of calculating row keys and allows the user to set the specific duration of each profile period. Based on this duration, each period starting at the epoch, is assigned a monotonically increasing value which is used as part of the row key. Periods can span multiple hours and there is no arbitrary durations that are unacceptable, like 5 periods per hour.
