with the payara-micro.jar command line i'm not seeing any way to specify a X.env file
of environment variables, or a X.properties file that has arbitrary jvm system properties.
(There is --systemproperties but as far as I can tell it is just used for payara. namepace).
So even though payara micro supports MP Config, I'm not see an easy way to specify
additional config values on the command line.
I'm also seeing no way to specify additional config *sources* (not just values) on the
command-line as part of permanent config -- just things i can maybe do in the
asadmin UI.
Right now I'm sourcing a file with a bunch of "export A=1" type lines in it, which seems
to work but isn't ideal.
