api: Introduce microverion 2.87 allowing boot from volume rescue

Browse Source 
Building on Ic2ad1468d31b7707b7f8f2b845a9cf47d9d076d5, when requested
this microversion will allow boot from volume requests to proceed when
the COMPUTE_RESCUE_BFV trait is also reported by the compute the
instance currently resides on.

Implements: blueprint virt-bfv-instance-rescue

Stable device rescue for boot from volume instances is now supported
through the use of the 2.87 microversion when the compute hosting the
instance also reports the ``COMPUTE_RESCUE_BFV`` trait such as the libvirt
driver.
No changes have been made to the request or reponse parameters of the
rescue API itself.
