Level 2 of economic sectors - with ISIC definitions

[FlorianLeblancDr]

I introduced the level 2 of economic sector (variable Value Added only for now), building on ISIC classification.

I build on @volker-krey comments made in #56
Giving variable used in the National Scenario template:

• level 3 categories (disaggregation of Industrial sub-sectors) are still missing
• I kept the ISIC names: thus the broad category "Energy" caterogy defined there is under "Energy All Supply Chains" now. Please let me know what you think of it
• I found it useful to add the Services "Commercial" sub-category, but did not disaggregated further services (will be done in level 3 as sub-categories or Others)

Please review @IAMconsortium/common-definitions-macro-economy

Bug are fixed
This PR is open for review now @IAMconsortium/common-definitions-macro-economy

Thanks, a few comments inline.

Does this really have to be a tier-1 variable?

Also, the top-level "Employment" variable was renamed to "Labour Force|Employed" in common-definitions. Consider revising here as well, or add a note attribute to cross-reference to the total-employment variable.

Please rebase this branch, and maybe also use this opportunity to copy all variables from macroeconomy_other.yaml to other relevant yaml files in the macro folder. Seems like there are now several files with a not-quite-obvious logic...

[FlorianLeblancDr]

Done (rebase + sorting macroeconomic_other.yaml).
Any Idea how to deal with Employment variables?

I don't mind making sub-categories such as
Labour Force|Employed|{sectors}".

@danielhuppmann first time I rebase on github, seems now in the PR appears changes already in the upsteam
but I did not had yet in my fork (MESSAGE mappings). Hope this isn't bad

[FlorianLeblancDr]

Rebase cleaned!
