Inefficient use of downloading entire pivnet product

[aegershman]

In order to extract the product name (and get the corresponding product GUID from the opsman), we're downloading the entire product from pivnet & looking at the metadata. Do we have to do this? Considering all we need is the product name?

Somewhat related: when uploading a stemcell, if opsman detects the version is already uploaded, it won't upload the stemcell again. Unless you pass in a "--force" flag.

Can we just pass around the metadata.yml file as input/output so we don't have to re-download the pivot product? That way we don't have to pass down the entire pivot product? Because all I need is the exact product_version.

Can we use some external store to save the tile metadata? Like a git resource? This might help #4 ...?
