Fix periodic NETCONF Call Home connection dropping

Callhome devices make reconnection every hour due to key re-exchange,
which is part of SSHD implementation.

When a specific session is authenticated and activated,
in case of key re-exchange, authentication (invoking of doAuth() method)
does not need to be made again.

Get rid of Netty's DelimiterBasedFrameDecoder

Netty's DelimiterBasedFrameDecoder is not really effective when dealing
with huge NETCONF messages and reading them in just really small parts
at a time.

DelimiterBasedFrameDecoder always searches whole input ByteBuf for
delimiter when new input bytes are available. It performs the search
also on bytes already checked in previous tries. Obviously, this can be
really ineffective when reading large messages by very small parts at
a time.

Replace Netty's DelimiterBasedFrameDecoder by our own frame detection
implementation. The implementation remembers already checked part of
the input ByteBuf and searches the delimiter just in a new bytes
available.
