### Description
Given all the shell files that now exist in the repo, would be nice to
have linting/formatting around them (in addition to the existing
shellcheck which doesn't do anything to format the shell code). This PR
introduces `shfmt` to both check for changes and apply formatting when
the associated make targets are called.
### Description
Update all other connectors to use the new downstream architecture that
was recently introduced for the s3 connector.
Closes#1313 and #1311
### Description
Add delta table connector and test against a delta table generated via
delta.io and uploaded to s3. Shows an example of how to use the
connection options to leverage s3.
I was able to get this to work with s3 if I pass in the access and
secret keys as storage options. Even though the s3 bucket being used is
public, would not work without those.
