Implement campaigns module with support for the Campaigns API (#257)

* Implement campaigns module with support for the Campaigns API

* update delete campaign tests

* Move jsdocs

* Update RecommendationContext

* Update CampaignRule types

* Update CampaignRuleInput

* Drop record

* Update CampaignParametersBase

* Update test

* Update type tests

* Rename module

* Refactor searchandising into campaigns sub-module

Split the flat searchandising module into a parent class that exposes a
campaigns sub-module, so each searchandising entity lives in its own class
and file. Consumers now call searchandising.campaigns.retrieveCampaigns().
Also drops the repetitive "Pull X from parameters" comments.

* Add retrieveCampaigns query param tests and type tests

Cover query params extracted from parameters in retrieveCampaigns (id,
refinedFilters, refinedRecommendationContexts, refinedQueries, plus their
snake_case aliases) and add the missing searchandising type tests.

* Type campaigns sub-module as an interface

Use an interface for the campaigns sub-module so the type file keeps a
single declared class, satisfying the max-classes-per-file lint rule that
also runs over .d.ts files in the pre-push hook.
