See comments on #1099 for context.

• slcli event-log get should support limits, and iterations
• slcli sg event-log should support looking up ruleIds instead of request ids i think. I don't think looking up the requestId is very natural for a user
• Add pagination to the event-log manager for getAllObjects
• Add support for custom limits to event-log manager. Should be able to request X amount of logs.
• Add read-the-docs style documentation for event-log stuff
