Consider refactoring the USER_CONFIG_OPTIONS template constant

[matthew-mizielinski]

In the code below the MIP Convert config template is set out, but for CMIP7 we are "breaking" this in several places by modifying it further down stream in MIP Convert .

We might need to pull out the constant into a function that can then modify the template depending on whether we want to work in a "CMIP6" or "CMIP7" style.
