Review Comment:
I updated the code as follows:
- to ensure the safety of the input `groupNames`, a defensive copy is
created which I use down the line when processing the input
- new unit test to cover the multi-threaded usage of this new utility method

> 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.
