This PS makes Deckhand raise an exception formatted including
the list ValidationMessage-formatted error messages following
any validation error. This adheres to the format specified
under [0].
To accomplish this, logic was added to raise an exception with
a status code corresponding to the `code` attribute for each
DeckhandException subclass. This means it is no longer necessary
to raise a specific falcon exception as the process has been
automated.
In addition, the 'reason' key in the UCP error exception message
is now populated if specified for any DeckhandException instance.
The same is true for 'error_list'.
TODO (in a follow up):
* Allow 'info_list' to specified for any DeckhandException
instance.
* Pass the 'reason' and 'error_list' and etc. arguments to
all instances of DeckhandException that are raised.
