Bigger installations (>200k services) tend to have a large WATO configuration with thousands of folders and hosts. Finding a host in these configuration took a considerable amount of time on some pages

Web API host calls, except add_host
Bulk discovery
Host diagnose
Fetching agent output
Service discovery
And some other pages, where the actual folder of the host is not known/specified

To fix this problem, a folder lookup index has been introduced to improve the time taken to find a hostname in the configuration.
