m/n/kubernetes: set PV inode quota relative to capacity
This removes the hardcoded 100k inode limit which is very low for large
PVs in favor of a scaled value dependent on its capacity. This
technically allows overcommit as the inode space is not accounted for on
the capacity side, but this was already the case before, just with a
static limit.
