Add request size limit configuration option

[petermasking]

Currently, we can't call remote procedures with a combined parameter size > 100kb. This is enough in most cases, but must be made configurable for all other cases (like Comify).

For the realization we need to dynamically set the limit of of the body parser.

Do we want to have it configurable for each and every route on the server? Or do we only want to have this setting apply to the rpc end point?

[petermasking]

I would suggest to start simple by applying it to all PRC calls.

So we don't increase the limit of the body on the health, jitar, etc. endpoints.

Thanks
