Use the new monitor command internal API to allow wrapping of the object
name and alias into the JSON props so that they don't have to be passed
out of band.
The new API also takes a double pointer so that it can be cleared when
the value is consumed so that it does not need to happen in every single

qemuBuildTLSx509CommandLine has no business guessing which alias should
be used. The alias needs to be passed in.
Note that there's a lingering bad design of this, since the secret
object alias is based on the device name and not on the fact that the
secret is used for decrypting of the TLS private key. If we ever add
authentication for chardevs this will bite us.
Thankfully disk code does not support encrypted private keys for TLS so
it can be happily refactored there.

Previously we did not store the aliases but rather re-generated them

when and which alias to use needs to be stored in the hotplug code as
well.
While this patch will not strictly improve this situation since there
still will be two places containing this code it at least will allow to
remove the mess from the disk-unplug code and will prevent introducing
more mess when adding blockdev support.
