rfc3339 date limit for time bound queries

[kostasb]

Summary: Time bound queries with rfc3339 are limited to 2050-01-01T00:00:01Z

Tested with both 0.13 and 0.14.0 head 1d467ab

ERR: time 2050-01-01T00:00:01Z overflows time literal

> precision ns

The limit seems to be hardcoded int64(2524608000000000000)

Querying with RFC3339 should support the same time range boundaries as ns precision.

The current maximum timestamp was changed to 2262-04-11 23:47:16.854775806 +0000 UTC at some point so I'm going to close this.
