Currently, swtpm TPM state file is removed when a transient domain is
powered off or undefined. When we store TPM state on a shared storage
such as NFS and use transient domain, TPM states should be kept as it is.
Add per-TPM emulator option `persistent_sate` for keeping TPM state.
This option only works for the emulator type backend and looks as follows:
<tpm model='tpm-tis'>
<backend type='emulator' persistent_state='yes'/>
</tpm>

This is perfectly valid in VMWare and the VM just boots with an empty drive. We
used to just skip the whole drive before, but since we changed how we parse
empty cdrom drives this results in an error. Make it behave more closer to
VMWare.

Currently, we configure QEMU to prealloc memory almost by
default. Well, by default for NVDIMMs, hugepages and if user
asked us to (via memoryBacking <allocation mode="immediate"/>).
However, when guest's NVDIMM is backed by real life NVDIMM this
approach is not the best. In this case users should put <pmem/>
into the <memory/> device <source/>, like this:
<memory model='nvdimm' access='shared'>
<source>
<path>/dev/pmem0</path>
<pmem/>
</source>
</memory>
Instructing QEMU to do prealloc in this case means that each
page of the NVDIMM is "touched" (the first byte is read and
written back - see QEMU commit v2.9.0-rc1~26^2) which cripples
device wear.
