Review KNet Connect SDK configuration (#1429)

[masesdevelopers]

Description

• Review KNet Connect SDK configuration
  The configuration is reviewed to identify and propagate default values defined in JVM side. Adds a new IKNetCommonConfiguration to simplify the access to configuration properties and updates the signature of the methods to introduce the new behavior. Task configuration in Source/Sink connector wasn't changed since it is a pass-through between connector and tasks

• Updates KNetTask Start method adding support for string only configuration values

• Adds IKNetTaskConfiguration to support configuration management from tasks

• Potential fix for pull request finding 'Missed 'readonly' opportunity'

• Fix task data exchange

• Fix NullReferenceException and adds logs when methods fails reporting .NET info
