Allow environment variables in node_service_prefix config. #7
Description
The config file's node_service_prefix is used to specify the string to prefix all locally connected services with to make them globally unique.
Today this is a static string.
It should support integrated Linux environment variables, allowing the prefix to be dynamically set depending on what the environment variable is set to.
Now we have a statically configured value.
jlr.com/vin/saw813433993cv4/
Instead we should have:
jlr.com/vin/$env{VIN}/
Where $env{VIN} is replaced by the value of the VIN environment variable.
We should also support file content:
jlr.com/vin/$file{/etc/vin}
Where $file{/etc/vin} is replaced by the single line stored in /etc/vin
