Allow usage of path params using generic request

[yehya]

This will allow providing a URL with params provided for a path like '/ex/:id/name' using the generic request method rather than using .put .get etc...

In this way the request can be done as follows:

const id = "123";
client.request<'/ex/:id/name', 'GET'>({ url: '/ex/${id}/name'}); // this rather than
client.get<'/ex/:id/name'>('/ex/${id}/name', {...}); // this

Being forced to use .get .post and others to allow for path params is more work than necessary.

Any feedback?
