[Types] Make queryParams strongly-typed

[sewera]

Right now, there are no types for queryParams; the default value is {}, so any object will match this type.

Some autocomplete will be nice, so I propose such alternative:

type GetListQueryParams = {
  page?: number
  perPage?: number
  sort?: string
  filter?: string
  expand?: string
}

// BaseCrudService@41
protected _getList<T = M>(basePath: string, page = 1, perPage = 30, queryParams: GetListQueryParams = {}): Promise<ListResult<T>> {
// ...
}

If it's okay with you @ganigeorgiev, I can make those changes and open a PR.

I can also merge the BaseCrudService and CrudService (resolve this todo) if you want me to :)

Hm, this was requested previously as part of #64.

For now let's keep the scope of the issue minimal and not merge the BaseCrudService and CrudService since this will require some major updates to the tests too.

We can add type for the query params but the declaration(s) needs to be a little more "relaxed" for better backward comparability and to allow setting also custom query props, eg. something like:

export interface BaseQueryParams {
    [key: string]: any;

    expand?:      string;
    $autoCancel?: boolean;
    $cancelKey?:  string;
}

export interface ListQueryParams extends BaseQueryParams {
    page?:    number;
    perPage?: number;
    sort?:    string;
    filter?:  string;
}

@sewera If you don't have the time to work on this, I'll implement it sometime at the end of the week.

I'll try to put together a PR with those changes by tomorrow.

[sewera]

@ganigeorgiev, please find PR #102 ready for review.

[ganigeorgiev]

The following types were added in master:

  BaseQueryParams
  ListQueryParams
  RecordQueryParams
  RecordListQueryParams
  LogStatsQueryParams
  FileQueryParams

They will be available with the v0.8.4 release sometime later this week.
