add dell backend init to service setup
initialize password auth client correctly in ssh module
have the dell backend use tellnet as their ssh implementation is b0rked AFAICT
include networkId in rejection message
change a couple of valueerrors to nsi payloaderrors
allow no orientation on stps
make it possible to specify payload dump when starting service
don't run nsi1 protocol as default (dual-stack probably won't happen anyway)
add proper label parsing and tests for it
slightly better label choice (enumerating all labels can be expensive and should be avoided
add method to determinte if label is a single value
