Expose Datahike Server Namespace

[alekcz]

Describe the feature you would like to request

I would like to be able add the datahike.server.http routes and functionality in to my current ring server (http-kit).

Describe the solution you would like

I would like the datahike.http.server namespace to be available in the datahike library (io.replikativ/datahike). With thisinternal-writer-routes exposed.

I would like to be able to do something like this (taken from reitit example code):

(def app
  (ring/ring-handler
    (ring/router
     (concat 
>>>>> (dhs/internal-writer-routes datahike-config)
      ["/api"
       ["/math" {:get {:parameters {:query {:x int?, :y int?}}
                       :responses  {200 {:body {:total int?}}}
                       :handler    (fn [{{{:keys [x y]} :query} :parameters}]
                                     {:status 200
                                      :body   {:total (+ x y)}})}}]])
      ;; router data affecting all routes
      {:data {:coercion   reitit.coercion.spec/coercion
              :muuntaja   m/instance
              :middleware [parameters/parameters-middleware ; decoding query & form params
                           muuntaja/format-middleware       ; content negotiation
                           exception/exception-middleware   ; converting exceptions to HTTP responses
                           rrc/coerce-request-middleware
                           rrc/coerce-response-middleware
>>>>>>>>>>>>>>>>>>>>>>>>>> dhs/datahike-middleware]}})))

Describe alternatives you've considered

I maintained my on fork of https://github.com/replikativ/datahike-server for 3 years but the maintenance overhead was not sustainable.
