Add filtering to api

[brauliodiez]

Here we can create a separate case, instead of two methods, let's have one

interface MoviesFilter {
  pageIndex,
  pageSize,
   filter // object
}

const getMovies = (filter: MoviesFilter = createDefaultMoviesFilter()) {
}

for the url filtering logic (api url generation) we can create a business method ina separate file and apply TDD to implement it.

const getMoviesByGenreUrl = `${getMoviesURL}?genres_like=${genre}`;

We should consider several cases, like, or exact string...
