Allow fuzzy string comparisons in $filter expr

Filter allows comparing certain strings as numeric greater than or less
than operators.  The most obvious example of this is something like

\$filter=Created gt <timestamp>

Because internally timestamps are treated as strings, this requires
including and parsing out the timestamps again, which we have utilities
for.

In addition, "fuzzy" string comparisons, like

GPU_2 gt GPU_1

Should also be supported.

Tested: Unit tests pass
