[elturkym]

This change allow AWS users, to store the database credentials in AWS Secret manager instead of adding the credentials in the configuration file directly.

Changes:

• Adding a new config aws_secret_name under target to store the data source name (DSN) which has the database connection info.
• Update the config.go to read the DSN from the given secret in the configuration file.
• Update the config.go to override the DSN from AWS secret manager.
• Update README file with the steps to use AWS Secret manager.

I think it's still not enough. We also need to remove heading and trailing slashes. Just like in the suggestion I made above. 🙂👍

[elturkym]

Thanks, will address that

[burningalchemist]

Hey @elturkym, do you need any help or assistance from my end to address the remaining issues? :)

I was trying to run the workflow locally before submitting a new PR, but let me raise a new PR and check if there is still an error
