The error message is not accurate when using pool cluster to create connection

[purejs]

Version: .2.2.0
Step to recreate:
Step 1: create cluster

var mysql = require( 'mysql' );
var poolCluster = mysql.createPoolCluster( );
var cfg =  {
    host:localhost,
    database: testdb,
    user: 'testUser',
    password: 'password' 
};

poolCluster.add( 'test', cfg );

Step 2: use cluster to connect db

poolCluster.getConnection( 'test', function( err, connection ) {
    if ( err ) {
        console.log( err ) 
    }
    // ...
} );

Result:
The error message is 'Pool does not exist', but actually, i just forget to set insecureAuth=true in cfg which causes the error of HANDSHAKE_INSECURE_AUTH.

Expectation:
The error message should reflect the reason why the pool does not exist or expose the error directly when creating connection not successfully.

Many thanks.

Thank you, I can confirm this. Looks like any connection error causes this behavior.
