Add nf-float 0.4.5 (#94)

Fixing a compatibility issue between MMC and AWS API.
The endpoint for AWS region us-east-1 is different with other
regions.  The algorithm used by MMC to provide the default endpoint
does not work.

Add support in nf-float plugin to retrieve the endpoint configuration
from `aws.client.endpoint` and supply this to MMC if available.

Do not change the default `scratch` option if user has local work dir.
