[NOC-356] Read industries metadata from SSOT

[infojunkie]

@rjkuyvenhoven I did some further refactoring - please test on your local machine when you get the chance.

One last thing I'd like to discuss with you is handling LMM industries which as you know are not mapping 1:1 to industry profiles. Right now, the mapping is done in 2 places:

• ssotIndustryLMMKey() when displaying LMM data on the Industry Profile page.
• LabourMarketEmploymentIndustriesTable::getIndustryHighlights() when displaying the LMM page itself - the only needed data here are the labels.

The first one can be handled more elegantly by simply renaming the LMM industry columns in the SSOT monthly_labour_market_updates endpoint to match the industries keys.

The second one is more problematic, because an LMM industry such as wholesale_and_retail_trade does not have an industry profile equivalent. I am reluctant to add an entry for it in the industries table, but it would still be great to have a way to read these labels from SSOT. I am thinking to read them from the SSOT schema of the monthly_labour_market_updates endpoint.

What do you think?

I've updated SSOT with the changes outlined above - to test, please refresh your SSOT with the dump in this branch.
