conf: Deprecate 'keymap' options

Defining the 'keymap' option in libvirt results in the '-k' option being
passed through to QEMU [1][2]. This QEMU option has some uses, primarily
for users interacting with QEMU via stdin on the text console. However,
for users interacting with QEMU via VNC or Spice, like nova users do, it
is strongly recommended to never add the "-k" option. Doing so will
force QEMU to do keymap conversions which are known to be lossy. This
disproportionately affects users with non-US keyboard layouts, who would
be better served by relying on the guest OS to manage this. Users should
instead rely on their clients and guests to correctly configure this.

This is the second part of the three part deprecation cycle for these
options. At this point, they are retained but deprecated them and their
defaults modified to be unset. This allows us to warn users with libvirt
hypervisors that have configured the options about the pitfalls of the
option and give them time to prepare migration strategies, if necessary.
A replacement option is added to the VMWare group to allow us to retain
this functionality for that hypervisor. Combined with the above, this
will allow us to remove the options in a future release.

Title:
  Remove nova default keymap option for qemu-kvm (deprecated)

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) pike series:
  In Progress

Bug description:
  Hi,

  Nowdays, qemu-kvm default keymap option -k en-us, or any keymap option
  is deprecated.

  In OpenStack it renders the web console access to vm unsuable even
  with the proper keymap in nova.conf. For exapmle the use of 'Alt-Gr +
  key' combination in French, Belgium, spanish, or alike keyboard is not
  working, this can be problematic for hard passwords.

  Using the linked patch and removing/commenting the keymap options in
  nova.conf, makes everything working again (depending on the NoVnc
  version which might be patched also on previous ones).

  So maybe by default the nova.conf should now comment/remove this
  option and we need to remove the default option in the nova code.

  Regards,
  Pierre-André
