Automatic abortion of queries

[Akron]

Different mechanisms should help to stop avoid ressource-hungry processes in KorAP. Some are already in place in separate components, but they should further be evaluated in the context of our architecture.

Mechanisms that are useful:

• using a user-specific timeout per search (already implemented in Krill)
• using a memory-limit
• catching http disconnections

(This was the result of a meeting with our colleagues from the BBAW.)

Search with user-specific timeout has been added in Kustvakt in 79d738c.
