Let "create server" set custom metadata

Fixes #37

When creating a server, custom metadata "os" and "users" are
automatically derived from the image properties. This commit
allows users to overwrite them or add extra custom metadata
at server creation time.
Escape control characters in HTTP body, when json

Fixes #32

This commit ensures that control characters are escaped in all
HTTP response bodies, as long as they are parsed as json strings
Raw content is kept intact
Response header contents were already handled correctly
Fix typo in server_create

Translate no-vnc console types from CLI to API

Fixes #36

The terms "no-vnc" and "no-vnc-encrypted" are expected to be easily
understood by users, while the equivalent terms vnc-ws and vnc-wss
(respectively) are used in Compute API. Kamaki CLI will now
accept both terms by internally translating the former to the later.
Report error in case of incorrectly encoded terms

Fixes #41

This bug was located at the code that parses the command terms.
If a term is invalid with respect to the current locale settings,
an "Unknown error" was being raised.
Kamaki is now reporting a descriptive error with a reference to
the faulty term.
