e4ebb5b384 Add trace statements for WebSocket messages
* With `logger.level: TRACE`, the content of WebSocket messages is logged
  together with the corresponding timestamp.
* The input is not further sanitized as this log level
  is not intended for production use.

36dc99f019 Don't embed the execution.Storer interface into a runner
Previously, the execution.Storer interface was embedded in the Runner interface.
However, this resulted in calls like runner.Add(...) to add an execution to the
store which is kind of ugly. Thus, we decided to add only the required functions to
the runner interface and make the execution.Storer a field of the implementation.

e2d71a11ad Avoid concurrent writes to the websocket connection
Previously, the server sometimes crashed due to concurrent writes
to the websocket connection. Now, we ensure that only one concurrent
function writes to the websocket at a time by enclosing the WriteMessage
function with a mutex.

8d24bda61a Send SIGQUIT when cancelling an execution
When the context passed to Nomad Allocation Exec is cancelled, the
process is not terminated. Instead, just the WebSocket connection is
closed. In order to terminate long-running processes, a special
character is injected into the standard input stream. This character is
parsed by the tty line discipline (tty has to be true). The line
discipline sends a SIGQUIT signal to the process, terminating it and
producing a core dump (in a file called 'core'). The SIGQUIT signal can
be caught but isn't by default, which is why the runner is destroyed if
the program does not terminate during a grace period after the signal
was sent.

8b26ecbe5f Restructure project
We previously didn't really had any structure in our project apart
from creating a new folder for each package in our project root.
Now that we have accumulated some packages, we use the well-known
Golang project layout in order to clearly communicate our intent
with packages. See https://github.com/golang-standards/project-layout
