Implement SailsQuery object to represent BLUEPRINT methods

[burntblark]

BLUEPRINT methods that are allowed through routes should be ready to use. https://sailsjs.com/documentation/concepts/blueprints/blueprint-routes

So I think using the same names https://sailsjs.com/documentation/reference/blueprint-api
it would be nice Because as LIB is for Sails I think it should follow the same nomenclature.

I say this because there are some methods like SAVE

ngx-sails-socketio/src/sails.query.ts

Line 43 in fcacfbd

public save(model: T): Observable<T> {

REMOVE Which in the case I believe should be called destroy.
Because the remove in BLUEPRINT is used for something else

ngx-sails-socketio/src/sails.query.ts

Line 83 in fcacfbd

public remove(id: string): Observable<T> {

AND findById that does not meet any Waterline or blueprint nomenclature.

ngx-sails-socketio/src/sails.query.ts

Line 33 in fcacfbd

public findById(id: string): Observable<T> {
