Merge network clients to a single class

There are two network clients as a base one and a JSON one. This
implementation way is different from the other projects' clients.
Now we need to implement a rest client method as a library function,
and it is necessary to make the rest implementations consistent now.
Then, this patch merges network clients to a single class like the
other projects' ones.
