Restore getTemplateURL() in template pull

Rework in openfaas#668 removed the call to getTemplateURL() which set `repository` to a value based on a precedence order.  This meant that an argument needed to be passed to `faas template pull` in order for it to complete without error, which had implications for pulling of the standard templates using the bare command.

This commit re-introduces the line which determines what value should be used for the repository before the code heads off into pullTemplate()

Add flags to control the log output format

**What**
- Add new flags to toggle the name, instance, and timestamp fields.
Additionally, the new `time-format` also allows controlling the actual
timestamp format.
- Also provide the log format flag to allow printing the output as JSON,
key-values, or the plain format.  This should make it easy to integrate
with other tools, like JQ etc.
