    Akash Provider safeguard script against freeloaders

This script issues akash tx market lease withdraw only against leases which ran out of balance.
Motivation

The deployment gets automatically closed when it runs out of balance in escrow account.
But the balance settlement occurs only after a lease withdraw transaction.
Without timely withdrawal from the escrow accounts freeloaders can deploy an expensive deployment
which will ran out of 5 AKT deposit by far and still be up & running until provider withdraws the lease.
The default --withdrawal-period is set to 24h which is too much for large providers and, at the same time,
setting this parameter to a low value would cause a lease withdrawal TX for every deployment causing unnecessary fee spending.
How it works?

It takes the active leases (akash query market lease list) per provider you set,
then it checks balance remaining per every deployment.
After that it withdraws from the escrow account (akash tx market lease withdraw) only those dseq's which ran out of balance.
It should run on a provider side or wherever it's got provider's key (for issuing akash tx market lease withdraw)
and the access to Akash RPC node for broadcasting that TX.
I suggest to wrap it into a shell script and add it to crontab to run every 1 minute.

# Note: [as per Adam] this script assumes that there is only one lease per deployment.
