Create and load config file with assigned variables

Hi,

I would like to create a configuration file(txt, csv, etc...) where I assign values to variable names and I want those variables loaded
so I can access them in my tests.

For example:

#server
server.ip=10.10.10.10
server.port=1234
username=name
password=password

#parameters
organization=123

I would like a flat file like this so I can make the changes in a text file when i change environments.
