monitor Ext2/3/4 fs

e2 plugin to monitor Ext2/3/4 fs mount count, last check and lifetime writes
update
pod added
Fixes bandwidth_ to successfully init new installs.

Previously the script would try to divide by 0 for calculating rates
on the first run, and crash before getting to store() to write initial
values thus never initing itself. This fixes that, and makes it a
little easier to debug in case of future crashes (no need for 'eval'
wrapper).
Allows setting warnings by environment variables.
