Bug #46822 Add smaller than 1 week period to purge logs/historical data in MEM

Description:
Currently the smallest period to purge logs/historical data is 1 week.
It would be good to be able to set smaller period.

Currently there is workaround to set it manually, for example using link like below:

http://localhost:18080/main?command=set_property&property=quan.lifespan&value=1

however it is always better to be able to do it via UI.

How to repeat:
1. Install MEM
2. Check settings tab

Need to investigate if this is an easy UI tweak (ie. no backend work required) to add support for shorter purge intervals - if so we can leave as a 2.1.x maintenance thing.

The smallest purge log time interval that could be set in the Dashboard was one week. MySQL Enterprise Monitor was changed to allow setting the smallest purge log time interval to one day.
