Expand list of keywords used for autocomplete and autocapitalize

Seems that CrateDB's admin UI has a much more rich list of such keywords, how about adopting this list for crash as well?

see: https://github.com/crate/crate-admin/blob/main/app/scripts/controllers/console.js#L409

Sure, good idea. Those other two tickets are also about the same topic of expanding the list of keywords.

• Keyword completion: Update SQLCompleter with keywords from aggregation functions? #360
• Keyword completion: Inquire pg_catalog.pg_proc table for scalar functions #401

This other ticket discusses the topic about loading keywords from CrateDB itself.
