Use JGit Config#getTimeUnit to parse durations

This simplifies the code and ensures more consistency with other
code using JGit.  It involves some changes to semantics:

- "0 sec" is a duration now!  Durations do not have to be nonzero.

- unfortunately, fractional units (like "5.2 sec") are not allowed any
  more.  You have to use integer expressions like "5200 ms".

- throws IllegalArgumentException instead of IllegalStateExpression
  for bad units

If disallowing fractional units proves too much of a hardship, this
can be fixed in jgit.
