[IMP] getawslog.py - move to boto3, logging, file in memory

[mpucholblasco]

Changes

• Moved from boto to boto3
• Applied logging
• Files content just handled in memory (no disk writes)
• Changed content to adapt to pylint
• Removed count a whole table rows to know if a table exists. Changed by a SELECT 1 FROM table.

Testing

By executing on a cloudtrail bucket.

Incompatibilities

• Changed options flag -l | --log meaning. Now this flag represents the log output filename. Previous meaning has been moved to -o | --output.
