Set credential flags

[henriquemoraeszup]

Description

• Adding flag capacity to the command rit set credential with provider, fields, and values. Fields and values are a comma separated list of strings.
• Simplified the user flow by removing the "add new credential from filepath" option. It does not seem to bring any value to provide a filepath for a txt file with a single credential value in it. Also there has not been any reports about user consuming this functionality

How to verify it

Run rit set credential --provider=github fields=username,token values=user1,token1

Changelog
