Bug 1115466

Description of problem:

When using jsonrpc, reconstractMaster send 8 arguemnts instead of 9 as specifed in the schema. The missing argument is the *first* one, the hostId.

The schema:

##
# @StoragePool.reconstructMaster:
#
# Recover a Storage Pool by reconstructing its Storage Domains.
#
# @storagepoolID:           The UUID of the Storage Pool 
#
# @name:                    A human-readable name for the Storage Pool 
#
# @masterSdUUID:            The UUID of the Storage Domain that will be used as
#                           the master domain
#
# @masterVersion:           The Storage Domain version of the master domain
#
# @domainDict:              Storage Domain statuses to be restored
#
# @lockRenewalIntervalSec:  The number of seconds to wait before renewing lease
#                           (Should be less than @leaseTimeSec).  0 selects the
#                           default value.
#
# @leaseTimeSec:            The maximum number of seconds that the leaseholder
#                           may retain the lease without renewing it.  0 selects
#                           the default value.
#
# @ioOpTimeoutSec:          The maximum number of seconds that an I/O operation
#                           may take to complete.  0 selects the default value.
#
# @leaseRetries:            The number of times to attempt lease renewal before
#                           failure.  0 selects the default value.
#
