Duration (TTL)

[andynataco]

Replace the current ttl variable in favor of duration. The duration type should have a numerical value and unit of time. Having the duration will allow partner to set a duration for 3 secs or 5 minutes.

@senojj If we are updating the docs to let the user know TTL is in seconds, is it necessary to change the type of it?

@Santiago-Torres14 duration would be an upgrade from ttl. This issue doesn't duplicate #22.
