In order to guarantee a secure connection between apps and the LCD the
communication must be encrypted - even if clients and server run on the
same local machine, credentials must never be transmitted in clear text.
Upon start up, the server generates a self-signed certificate and a key.
Both are stored as temporary files; removal is guaranteed on exit.
This new behaviour is now enabled by default, though users are provided
with a --insecure flag to switch it off.
These method were surprisingly slow from the profiling.
(Mapper.Get accounted for 2.7% of time taken, GetKey also took an
interestingly large portion of time)
This is to facillitate ease of implementing #1406. (Tags for messages
could then be added dynamically)
Ultimately once we make the router support hiearchical routing, (#770)
we can then remove the name field and just the parse info for tags from that.
Until then, we can parse the tag name as
`fmt.Sprintf("%s %s", msg.Type(), msg.Name())`
