[Feature Request]: Pull operating system environment variable

[CarlosJuncher03]

What would you like to happen?

The ability to retrieve operating system variables that we define for the user or for the entire system within Apache Hop. An example of this is the dynamic creation of a file connection; I can define a variable in the system that dynamically returns the date, thus creating the connection dynamically.

jdbc:h2:${java.io.tmpdir}/${HOP_PROJECT_NAME}_${system_variable};AUTO_SERVER=TRUE

ADD them to the HOP_OPTIONS variable using -Dvariable.name and they are available in the application

[CarlosJuncher03]

In the case of hop_gui.sh, put it like this?

if [ -n "${MY_DATE}" ]; then
HOP_OPTIONS="${HOP_OPTIONS} -DMY_DATE=${MY_DATE}"
fi

You were talking about system variables, https://hop.apache.org//manual/latest/installation-configuration.html#_set_system_environment_variables you can add a system variable called HOP_OPTIONS and add all those fixed variables that you want to send to all hop commands
