Remove errors.ConfdFatalError
This exception is caught, but never thrown. It became useless when wemoved confd from on/off to enabled/disabled, but always running on allnodes. Removing its definition and the code catching it can do no harm.

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

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.
