fix(crud): merge crud options from methods and classes

[Diluka]

Since CrudRequestInterceptor can be used detached, there is a problem about the incoming query and the static built-in query. Every methods which use CrudRequestInterceptor out of crud can have a options by their own. The search option solved the problem about query merge. But comes a new one that the filter set after req created does not take effect. So put this options in method's metadata and CrudRequestInterceptor gets from it before req created to make it work.

use SetMetadata(CRUD_OPTIONS_METADATA, { query, params }) in my custom decorators and CrudRequestInterceptor will get this from method.

I am trying to help and have forked this repo (can't reach the owner of this repo and do not have the credential for the npm repo).

See #710 (comment)

We can hopefully merge it via rewiko#5
