This adds a shard-based import endpoint which takes bitmap data for
all field types and imports data for the whole shard transactionally.
It uses the BitmapRewriter interface to try to intelligently allow for
setting and clearing bits simultaneously without multiple writes which
is especially helpful when ingesting into int-like fields, but also
allows clear-and-then-set behavior for set fields.
When you backup a cluster, we call /schema which marshals timestamp field options to
json, and restores the fields with those options. If the min and max are missing,
they are set to 0 on restore, which causes an issue on subsequent ingest.
Fixes [SUP-213](https://molecula.atlassian.net/browse/SUP-213) and
[FB-1332](https://molecula.atlassian.net/browse/FB-1332)
this stems from https://molecula.atlassian.net/browse/SUP-194 where the string
"standard" was being passed to viewTimePart, which output "standard" as the result.
this is not a valid time string and was causing confusing errors. now it simply
doesn't do that
this commit also adds regression testing framework and a regression test for fb-1287
