RAPI: switch evacuate node to the new model
This patch removes the last use of the old-style OpEvacuateNode. It alsofixes the dry-run mode for this RAPI resource - the dry-run parameterwas not used at all before.

RAPI client: Improve SSL error reporting
RAPI client: Don't check node role in client
Only the server knows which node roles can be set via RAPI.Constants are provided for convenience.
RAPI client: Update ReplaceInstanceDisks
- The RAPI client shouldn't check the replacement mode as only the server knows which ones are valid (constants are still provided for convenience)- Disks shouldn't be a list of names, but of indexes
RAPI client: Fix behaviour of “allocatable” storage flag
When modifying a storage unit, the “allocatable” flag should defaultto “no modification”. This replicates the behaviour of the commandline interface.
RAPI client: Encode boolean and None query values
Boolean values must be passed as 0 or 1. None should be an emptyvalue ("").
RAPI client: No longer check storage type locally
Only the RAPI server (actually masterd) knows which storage typesare valid. The exception can no longer be raised as the type isonly checked in the job.
RAPI client: Add constant for RAPI version
This reverts a60e3cb0a partially by moving the RAPI version into a constant.

rapi: Don't access request's private object directly
This way the request handlers don't need as much knowledgeabout the inside of the request and context objects and itmakes the code a bit shorter.

The HTTP layer shouldn't care about the contents of the request data orresponses. This requires further changes in the RAPI code to handle clientrequests correctly.

Further pylint disables, mostly for Unused args
Many of our functions have to follow a given API, and thus we have tokeep a given signature, but pylint doesn't understand this. Therefore,we silence this warning.
