Represents a connection to a MySQL server.

`connection`is the main I/O object that this library implements. It owns a `Stream` object that is accessed by functions involving network operations, as well as session state. You can access the stream using `connection::stream`, and its executor via `connection::get_executor`. The executor used by this object is always the same as the underlying stream.

##### Thread safety

Distinct objects: safe.

Shared objects: unsafe.

This class is not thread-safe: for a single object, if you call its member functions concurrently from separate threads, you will get a race condition.
