related Project: https://github.com/DivanteLtd/storefront-query-builder/
closes #2167 and partially #2232

1. I've added new SearchAdapter api-search-query which is just passing the raw SearchQuery to the backend - no bodybuilder imported
2. I've moved the SearchQuery and queryBuilder to separate repo https://github.com/DivanteLtd/storefront-query-builder which is now shared between vue-storefront and vue-storefront-api and will be shared with storefront-api as well
3. For backward compatibility - there is just one change required: config.api from api-search-query to api. No other changes required.
4. I've removed amp-renderer module (it's disabled in the src/modules/index.ts)
5. I've removed google-tag-manager module (it's disabled in the src/modules/index.ts)

Note: If you still need bodybuilder it's in the package.json so you can just use import bodybuilder from 'bodybuilder' - that's it.

Testing instruction

• Deploy the vue-storefront-api that supports search-query: feature/2167 vue-storefront-api#390
• Change the config: config.server.api to api-search-query; recompile API + frontend

Overall effect: simplified business logic (no Elastic DSL construction in the frontend); -400kB over app.js bundle

Next steps:

• fix Unit tests,
• update changelog,
• update upgrade notes,
• fix warnings caused by amp-renderer module disabled
• finish the vue-storefront-api part - currently, it's missing some important config variables so the final query is not properly built,
• add a readme file to the storefront-query-builder and continue the extension works as requested in Extendable Elasticsearch queries #3934
