This adds a new microversion to expose the instance action
event details in the
GET /servers/{server_id}/os-instance-actions/{request_id} API.
With the new microversion the "details" key is always returned
with each event dict but the value may be null because of old
records or events that did not fail.
The details are not constrained by policy like the traceback
field since the details are like a fault message on the server
resource when the server is in ERROR status and the fault
message is likewise not constraint by policy unlike the fault
details which is a traceback like the event traceback field.
This commit add a SYSTEM_READER ('rule: system_reader_api') role
to the Show Server Action Details API. With this default policy,
events fault details can be displayed. And also add some nova and
non-nova exception functional tests for os-instance-actions API.

If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems.
