Adding support for transaction savepoint

var knex = require('knex').initialize({..});

var q1 = knex('books').insert({ name: 'Canterbury Tales' });
var q2 = knex('books').insert({ name: 'Moby Dick' });

knex.transaction(function(t) {
  return q1.transacting(t).then(function(a) {
    return knex.transaction(function(t2) {
      return q2.transacting(t2).then(function(b) {
      });
    });
  });
}).then(function() { console.log('fine'); process.exit(0); },
        function() { console.log('problem'); process.exit(1); });

This script succeeds under normal operation on a simple books schema. But under pool: { max: 1, min: 1 }, it hangs.

Let’s close it and see if anyone yells 😃

P.S. I confirmed it on the internal maintainer chat first 😄

Yeah, I hadn’t gotten around to it yet but I’d like to add support
