chore: remove deprecated config

[EnriqueL8]

• Remove deprecated config for blockchain, tokens, factory, database, dex and shared storaged config

This was discussed in Discord with contributors, including @awrichar

Marking migration consideration to ensure it's included in the V1.3 migration notes when they are built.

I see you've got a swagger mismatch:

        	Test:       	TestDiffSwaggerYAML
        	Messages:   	The swagger generated by the code did not match the swagger.yml file in git. Did you forget to run `make reference`?

Currently until #1233 is merged, if you build make reference locally with Go 1.19/1.20 it generates a different set of YAML fields to the build that runs in Github actions with 1.18. So you might need to check in your local dev env you run make reference with Go 1.18.

Noticed a coverage drop - so popped in an extra commit to help this close out
