High disk consumption

After the first 10h of the testnet I think that some participants could run out of space.
We are in around 0,7G / hour consumption at the start of the network (maybe higher cos snapshots and DB initialization). It got stabilized to 0.42G / hour after this.
I wonder if we could add a hard pruning strategy to all the containers.

Minor changes suggestion:
Add

--pruning=everything

to this line:

kira/docker/kira/container/validator/start.sh

Line 137 in a511451

sekaid start --home=$SEKAID_HOME --trace

and here:

kira/docker/kira/container/sentry/start.sh

Line 110 in a511451

sekaid start --home=$SEKAID_HOME --grpc.address="$GRPC_ADDRESS" --trace

Thank you, added pruning to branch asmodat3, tesntet branches will be updated shortly
