Standalone Server

[therustmonk]

The first feedback shows that a separate server that supports multiple providers is required.

Embedded Server + Dashboard are very useful things, but for fast checking and trying the library.

For prod usage support of multiple connections required. Since it is not easy to maintain many server versions, we are going to release and support a standalone server only and hold the embedded one for a while. As soon as the standalone server becomes fully functional we will detach some parts back to the standalone server and release/embed it again.
