[PATCH v2 01/12] qemu: command: Generate commandline of 'masterKey0' secret via JSON

[Peter Krempa <pkrempa@xxxxxxxxxx>]

While the 'masterKey0' secret object will never be hotplugged we want to
generate it through JSON so that we'll be able to validate all
parameters of '-object' against the QAPI schema once 'object-add' is
qapified in qemu.
