Improve Error Message for Client Initialization in Salesforce connector

[RDPerera]

Current Limitation

The client initialization with the password grant type works fine locally. However, when deploying it in Choreo with the same configuration, the following error is encountered:

Invalid values provided for client configuration parameters.

This error is shown regardless of the actual reason for the failure, which can be misleading.

(This issue is solved for 2201.8.x but need to be fixed for 2201.9/10.x)

Suggested Improvement

Change the error message in here and other modules into a meaning full error message.
