Description

The template cache is currently just a map per segment. This is problematic in various ways:

• A segment needs to be in memory and probably loaded first only to read something from the cache.
• No monitoring, instrumentation of the cache
• No control over memory consumption

We should there for come up with a proper template cache implementation in the same way we have done for strings (StringCache) in OAK-3007. Analogously that cache should be owned by the CachingSegmentReader.
