KUDU-2636: LBM supports deleting dead containers

this patch intends to support deleting the full containers
that are dead at runtime. It can help to ease disk pressure,
save tserver startup time and etc. It uses the container
size and live blocks to determine whether the container
is dead or live.

Step1: wrapping up containers in scoped_refptr. [V]
Step2: supporting dead containers removal.      [V]
