Push to S3

[abradley60]

• Adding function to upload files in a local folder to a specified s3 bucket and folder
• The substructure of the specified folder will be maintained
• Adding a command line tool that can be called
• Added the default logging level of 'info' to the cli.py script

Thanks for this Alex!

Before merging:

• Can you please update the environment.yml file to include boto3 and dependencies? I needed to do pip install boto3 to get it working
• Perhaps include an option to allow a user to upload a whole folder (e.g. my-folder/folder bucket my-s3-folder would create my-s3-folder/folder which contained the files)

Looks great and works well otherwise, so happy to approve :)

@caitlinadams the following changes have been made:

• Added dependancies for environment
• renamed the cli from push_folder_to_s3 -> upload_files_in_folder_to_s3 for clarity. The --upload-folder flag can be set to indicate the whole src_folder should be uploaded to the specified s3_bucket_folder, rather than just the files and subfolders inside of the src_folder.

Let me know if any other changes needed
