A library containing standardized trait strings. Used by placement service and clients to ensure consistency.

The main motivation for this change is to: (a) add missing CPU flags
(including those flags that provide mitigation for the recent CVE flaws)
as 'traits'; and (b) adjust and clean up the layout of the 'hw/cpu/'
directory.
To that end, the following are the set of changes in this patch.
(*) Introduce a new cpu/x86 directory; and vendor-specific files: amd.py
and intel.py; with __init__.py containing the *common* stuff:
- hw/cpu/x86/amd.py -- AMD-only traits.
- hw/cpu/x86/intel.py -- Intel-only traits.
- hw/cpu/x86/__init__.py -- Common traits for both AMD and Intel.
- hw/cpu/x86.py -- Two things: (a) move the contents of this file
into x86/__init__.py, which is its new location; this move
preserves the integrity of the string trait names and Python
paths, as they were before; and (b) given point (a), remove the
now no longer needed hw/cpu/x86.py. (Justification: We are
removing this file to maintain consistency with the way it's done
througout the 'os-traits' repository.)
- hw/cpu/amd.py -- Deprecate the contents of this file with a
comment; and copy them into hw/cpu/x86/amd.py, which is its new
location.
Comparison between the old and the new layouts of os_traits/hw/cpu/:

(*) Add various missing CPU flags to x86/intel.py, x86/amd.py and to

(*) Copy, and deprecate with a comment, flags from cpu/x86.py, i.e..
"VMX" (Intel) and "SVM" (AMD), into corresponding vendor-specific
files.

os-traits
os-traits is a library containing standardized trait strings.
Traits are strings that represent a feature of some resource provider. This library contains the catalog of constants that have been standardized in the OpenStack community to refer to a particular hardware, virtualization, storage, network, or device trait.
