[KNOX-3035](https://issues.apache.org/jira/browse/KNOX-3035) - Group header
value should be based on data size and not number
## What changes were proposed in this pull request?
Until now, the `KNOX-AUTH` service and the configurable dispatch code
supported the partitioning of optional group headers in the response by length.
This PR adds support for size-based partitioning in a way, such that it
takes precedense of the already supported length-based chunks, if the
size-based configuration is set to a non-negative value.
New configuration:
- in the `KNOX-AUTH` service: `preauth.auth.header.groups.size.limit`.
Defaults to `-1` to preserve backward compatibility with previous Knox versions.
- in the service dispatches: `groupHeaderSizeLimit`. Defaults to `-1` to
preserve backward compatibility with previous Knox versions.
## How was this patch tested?
Updated existing unit tests and added new tests for the new utility class to
cover all cases and ensure that partitioning works as expected.

> KNOX-2974 and KNOX-3023 support adding group headers to requests flowing to
> downstream endpoints. Currently the groups headers is based on number of
> groups (1000 default). A lot of webservers and loadbalancers support header
> sizes between 4KB - 8KB which be an issue when header sizes are large.
> This JIRA is to update this logic to limit groups in one header to configured
> size in KBs.
