Relaxing float comparison on fuzz testing

[alanprot]

What this PR does:
Relaxing a bit the float comparison on the fuzz test.

Currently, we allow floats to differ an absolute margin (1e-6). This PR is also allowing the floats to differ by a relative fraction (1.e-10 or 0.00000001% - this is less than 1 second if the result is a epoch now) .

This helps prevent fuzz test failing when the result number is relatively big, ex:

  query_fuzz_test.go:397: case 0 results mismatch.
        range query: avg(exp({__name__="test_series_2"}))
