Ability to use .aws/credentials instead of typing in the keys

Is your feature request related to a problem? Please describe.
It is frustrating to type/paste in your keys each time for each DB you want to connect.

Describe the solution you'd like
Would be great if the app allowed to select a profile from .aws/credentials instead of typing in the keys. You usually have your credentials handy in the config files for AWS.

Additional context
AWS credentials parser should probably populate the available profiles as a dropdown list.

+1 for this issue. Good work BTW

+1 also because we use a central identity account and switch roles into the client account.

This would also fix the session token issue where "AWS_SESSION_TOKEN" is not able to be added to the connection.
