Rename auto-detected facets
As a result of Fingerprinting incoming log lines, we auto-detect tokens like numbers, IP address, duration, size, and UUID. These tokens are automatically assigned log facet names as _number_0, _ip_address_0, _duration_0
respectively. These auto-assigned log facet names can be renamed to something more readable by the user from the log event detail view. The renaming is scoped to a fingerprint.

Fingerprints View
Fingerprints view provides a concise view of the unique logs ingested by the stack. This bird’s eye view is very helpful when looking at the huge number of logs that are typically emitted by production systems. For example, by filtering the logs by severity level of ERROR, the user can easily highlight different kinds of error events that are being observed by the system without hunting for them one by one. The fingerprints can be searched just like log events. Moreover, the logs can be filtered to only include/exclude logs with the selected fingerprint. This serves as a smarter grep where you can quickly filter logs without finding unique strings to grep or grep -v by.
