Description of change

Fixes #9890.

I have updated the SapDriver to use Node.js Connection Pooling, as pointed out by hdb-pool repo: https://help.sap.com/docs/SAP_HANA_CLIENT/f1b440ded6144a54ada97ff95dac7adf/e252ff9b2cb44dd9925901e39025ce77.html?q=connectionLifetime

I've also managed to connect with HANA express and run some tests. However, since the tests are too generic, there are some scenarios which fail as they do not exist on HANA.

Hi @dcdieci, it is ready to be merged. I've managed to establish a connection with HANA express by running the tests.
