Simplify basic usage (hide Thrift details)

[arikfr]

Current basic usage example:

const driver = require('databricks-sql-node');
const { TCLIService, TCLIService_types } = driver.thrift;
const client = new driver.DBSQLClient(
    TCLIService,
    TCLIService_types
);

client.connect({
    host: '********.databricks.com',
    path: '/sql/1.0/endpoints/****************',
    token: 'dapi********************************',
}).then(async client => {
    const session = await client.openSession();
    const response = await session.getInfo(
        TCLIService_types.TGetInfoType.CLI_DBMS_VER
    );

    console.log(response.getValue());

    await session.close();
}).catch(error => {
    console.log(error);
});

Let's simplify it to be:

const driver = require('databricks-sql-node');
const client = new driver.DBSQLClient();

await client.connect({
    host: '********.databricks.com',
    path: '/sql/1.0/endpoints/****************',
    token: 'dapi********************************',
});

const session = await client.openSession();
const response = await session.executeStatement("SELECT 1");

// TODO: probably need to change the following
console.log(response.getValue());

await session.close();
