Related Issue

• Auth fails for the DocumentDB which uses SCRAM-SHA-1, in which password is not shared and challenges are used for authentincation.

Closes: #1016

Describe the changes you've made

Added functions to generate the new responses of the SCRAM authentication requests. And uses these functions to pass authentication in test mode for the DocumentDB which uses SCRAM-SHA-1. The user have two ways to pass the authentication for testing:

• Change the password of the user application to a dummy password(default123) for testing environments. Example: if an API is using an environment variable MONGO_PASSWORD for the creating a mongo url to connect. Then, change the value of the environment variable to "default123" for testing environment so that the keploy generated testcases pass.
• Or user can use the --mongoPassword to use their password with which they have recorded the testcases.

Please let us know if any test cases are added

Have used the sample-go/gin-mongo, tested the changes along with documentDB.
