Feature request: Support supplying config through a string and/or stdin #450
Description
It would be convenient if there is a --config-string and/or a --config-from-stdin option in ferron for supplying ferron configuration entries. Currently when I am using ferron to startup a test server for unit testing, I have to use a temp file with a ferron config and I have to ensure it lives long enough until the tests are complete and then ensure it is properly removed after all tests are done.
