Use utility functions for HMAC

HMAC will be used in more places. Centralizing some parts can't hurt.

Add targetted pylint disables

This patch adds targeted pylint disables, where it makes sense (either
due to limitations in pylint or due to historical usage), and also a few
blanket ones in rapi where all the names are… “different”.

Fix serializer unittests

Commit d22b29997cd broke the serializer unittests with certain
versions of simplejson. This patch removes sort_keys again

Serializer, remove salt_verifier functionality

The salt needs to be returned anyway, so we don't have to add another
key for the sender to recognize which request an answer is answering, so
all that infrastructure is useless. :(

Fix python 2.4 compatibility

I got overexcited and forgot we have to remain compatible with python
2.4. With this patch we move from sha256 to sha1 for hmac authenticated
serialized messages, and we handle both newer and older python, by
importing the right module for each....

HMAC authenticated json messages

This patch includes HMAC authenticated json messages to the serializer.
The new interface works on any json-encodable data type, and can sign it
with a private key and an optional salt. The same private key must be
used upon message loading to verify the message....

Fix epydoc format warnings

This patch should fix all outstanding epydoc parsing errors; as such, we
switch epydoc into verbose mode so that any new errors will be visible.

serializer.DumpJson: Control indentation by parameter

If the simplejson module supports indentation, it's always used. There
are cases where we might not want to use it or enable it only for
debugging purposes, such as in RPC.

Make sure serialized data ends with EOL character

Also fix the regular expression to not remove newlines. The simplejson
module puts whitespace at line endings when using indentation. Remove
unnecessary import of ConfigParser module.

Forward-port: Alias Dump/Load functions in ganeti.serializer to DumpJson/LoadJson

The remote API will use JSON for the foreseable future, so it's better
