Subject: [PATCH] add map size setter (#1050)

Add a bound the txpool db, rather than leaving it as the default of 2TB.
This is to reduce the page file profile when running multiple nodes from
around 3.5GB per txpool instance.

The current pool map side is set to 512MB - which seems reasonable with
16MB increments
