[darenasc]

Is your feature request related to a problem? Please describe.
Currently, aeda allows to profile one database at a time. Ideally, it can accept a list of connections defined in databases.ini and process them in parallel or sequence, using only one API call.

Describe the solution you'd like
A clear and concise description of what you want to happen.
The explore call can receive a list of database connections separated by space and generate a queue to process them, the last database connection should represent the target metadata database.
