Bug Fixes

Fix recursion error when METAFLOW_DEFAULT_ENVIRONMENT is set to conda

Prior to this release, setting default execution environment to conda through METAFLOW_DEFAULT_ENVIRONMENT would result in a recursion error.

METAFLOW_DEFAULT_ENVIRONMENT=conda python flow.py run

  File "/Users/savin/Code/metaflow/metaflow/cli.py", line 868, in start
    if e.TYPE == environment][0](ctx.obj.flow)

    if e.TYPE == DEFAULT_ENVIRONMENT][0](self.flow)

RecursionError: maximum recursion depth exceeded

This release fixes this bug.

Allow dots in host_volumes attribute for @batch decorator

Dots in volume names - @batch(host_volumes='/path/with/.dot') weren't being santized properly resulting in errors when a Metaflow task launched on AWS Batch. This release fixes this bug.
