b48b45de9f Refactor error classes
All runner errors are now in a single file. The not found error
has been splitted into an error for runner not found and for
environment not found.

413f9b2705 Improve error resilience and handling
Timeouts are now handled correctly and the Runner automatically
creates the execution environment if it could not be found in
Poseidon. The runner is deleted locally if Poseidon returns
a bad request error.

d0d1b1bffd Introduce strategy for runner behavior
The runner model is only a class responsible for storing information
now. Based on the configuration it picks a strategy for the runner
management. The Poseidon strategy is already implemented and tested.
The Docker strategy will follow.

d5b274c9f2 Introduce new error types for runners
The errors are raised in the runner model and in the runner connection
class. In the submission controller the errors are rescued and,
depending on the error, the status timeout / container depleted is
sent to the client.

8d968e01e6 Move RunnerConnection into class Runner
The old approach was to require the runner connection. This did
not work anymore with Zeitwerk in Rails 6. @sebastian.serth and I
moved the Connection class in `lib` into the ActiveRecord class
`Runner`. This will also work with future changes like specific
error classes. Furthermore the config was fixed and simplified.
