Add option to strip metadata when replaying events

[cortadocodes]

Feature request

Use Case

Our log messages have lots of metadata (datetime, parent SRUID, child SRUID, question UUID etc.). This is useful but sometimes we just want to see the logs. We'd like an option in the EventReplayer to strip this metadata and just show the log messages.

Current state

Metadata is always shown, making log message fill the screen and sometimes beyond.

Proposed Solution

Add strip_log_metadata or similar parameter to EventReplayer.
