Support for "filter by time" in heroku logs command

Feature / Enhancement Request
-----------------------------------------------------
Update the `heroku logs` command to support filtering the logs by time.
Adding options like :
{
`-h (default h=1), --hour=hour` : output logs only from past `hour` hours,
`-m (default m=1), --minutes=minutes`: output logs only from the past `minutes` minutes ,
`--seconds=seconds`: output logs only from past `seconds` seconds (for processes that dump alot of logs each second)
}

What is the current behavior?
-----------------------------
No options to filter by time in the `heroku logs` command.

What is the expected behavior?
------------------------------
`heroku logs` getting updated to have option to filter by time as described in the feature request section.
