Allow setting connect/read/write timeouts for requests

Right now there is no option to control the default timeouts (connect / read / write) for requests that are defined by the Nextcloud Files App. E.g. the Nextcloud News App makes a long running request for adding new feeds. The duration is basically determined by how fast the server is because the request will wait until the feed has been added successfully on the server side.

Therefore allowing single requests to have a longer / different timeout would be ideal.

I found an interesting article where someone explains a way to set timeouts dynamically via Headers that will be interpreted by OkHTTP later on. I believe this setup would fit perfectly fine into the SSO Lib: https://www.jndiary.com/post/setup-timeout-dynamically-with-retrofit

Leggi l’articolo collegato sui timeout dinamici di OkHTTP, quindi esamina il percorso delle richieste di SSO Lib per individuare dove vengono configurate le richieste di Nextcloud Files App. Determina come devono essere forniti i valori di timeout di connessione, lettura e scrittura per ogni richiesta e verifica che una richiesta di lunga durata possa usare valori predefiniti diversi senza modificare le altre richieste.
