cURL File Resource

This is a useful resource for pipeline development time, while a required artifact is available only from a URL-addressable location and until it is moved to a file management repository such as git or S3.
url: Required. The url location of the file.
filename: Optional. The name of the file for the downloaded artifact to be save as. If not provided, the file will be saved using the full url string as its name.

check: Check for the latest version of the file.
The resource uses
curl under-the-covers to post a GET request and retrieve the HTTP header info for the file URL provided.
Last-Modified is returned as part of the HTTP response header, then the resource will use that to build a version number timestamp with format "YYYYMMDDHHMMSS".
Otherwise, the timestamp string will be built using the request's current time, which will result in a new version being returned every time
check is executed for that file.
To verify if a file URL returns the
Last-Modified information in its HTTP response header, issue the
curl command below and search for field "Last-Modified" in its output.
curl -I <file-url>
in: Download the latest version of the file.
Downloads the latest version of the file issuing a
curl command under-the-covers.
