Larger context for a group of users

[margaretha]

There is a requirement to be able search with a larger context (surface text) exceeding usual restriction (token context limit), for a particular group of users.

[margaretha]

We decided to break this case into 3 level of configurations:

1. System wide (Krill configuration)
   Default setup in a config file. This should be security boundaries.

2. Instance wide (Kustvakt configuration)
   An additional setup may be configured in Kustvakt configuration, that may be different from the one in the Krill config (1) but should not exceed the security boundaries in the Krill config. Kustvakt should check requested contexts based on the numbers in its config, and add rewrite when the requested contexts are larger than allowed.

3. User wide
   Kustvakt manage which users may have larger context through query rewrites.

The 1st option is done in Krilll (see KorAP/Krill#128)

There was a misunderstanding regarding the 2nd option. Kustvakt should not change the default setup as it serves security measures. Kustvakt may change context size using rewrite.
