Log Errors Before Returning

[ThisaruGuruge]

Description:
Currently, when a GraphQL resource returns an error, it does not log the error. Users have to manually log the error when an error occurred.

To make the GraphQL library consistent with the other standard library, the errors should be logged before returning. Additionally, there should be an option to disable the logging.

After an offline discussion, the following conclusion was made.

• For Update 2, we are only supporting this for Query and Mutation operations. (Subscriptions not supported).
• The log:printError() API will be used to print the error log which will consist of the following:
  • The message
  • The stacktrace

Edit: Removed the error from the log since it duplicates the message
