v0.1.7: Fix several minor practical things

I've been running this version internally for a while and want to make
it available to others.

v0.1.6: Only create `/pfs/out` once (bug fix)

This fixes a bug in the v0.1.5 release. We need to get some on-cluster
integration tests up and running to catch things like this.

v0.1.5: Bulk insertions & `/scratch` cleanup

This should start jobs a bit faster, and correctly clean up `/scratch`.

v0.1.4: Print more detailed errors from `falconeri-worker`

Include the entire error chain, plus the backtrace (for now). This will
make it easier to debug problems calling `gsutil`.

v0.1.3

v0.1.3: Generate JSON schema for jobs

v0.1.2: Add basic S3 and Kuberentes secret support

We now support `tranform.secrets` and `s3://` URLs for inputs and outputs.

v0.1.1

v0.1.1: Fix binary releases
