knife kitchen command should be idempotent
Merge pull request #104 from avit/master

Use more complete host name parameter in unit tests

Also reorder some test methods.
Add --node-name option to specify node config filename

By default the node configuration is written to (by `knife prepare`) and
read from (by `knife cook`) "nodes/<hostname>.json". The "<hostname>"
part can now be overridden using --node-name option.

This is particularly useful when provisioning cloud servers that have
dynamic DNS names. The option is also consistent with `knife bootstrap`,
`knife ec2 server create`, etc.
