fix(retention): fix time-based retention

[trialiya]

There was a bug when maxAgeInSeconds (Integer) is greater than Integer.MAX_VALUE / 1000 (about 24 days). For example, if maxAgeInSeconds = Integer.MAX_VALUE / 1000 + 1, then maxAgeInSeconds * 1000 = -2147483296, and therefore all previous versions will be deleted.

Another option to fix this is to change the type of maxAgeInSeconds into long:

datahub/metadata-models/src/main/pegasus/com/linkedin/retention/TimeBasedRetention.pdl

Lines 6 to 8 in 088e7a8

	record TimeBasedRetention {
	maxAgeInSeconds: int
	}
