Earlier code introduced in[1] aimed to handle the situation where a
context object serialized and sent over a message queue as a
dictionary is received by a version of code that doesn't necessarily
understand that context object.
That code relied on the fact that vars(TroveContext).keys() was a
dictionary that matched the full set of parameters that you can send
to the initializers for TroveContext() and RequestContext().
Recent changes in oslo.context [2] and [3] broke that
assumption. vars() on TroveContext provided a dictionary with the
internal representation(s) that are not the same as the kwargs in
RequestContext() and the params that TroveContext used to pop.
To get around this, new code introduced here uses
oslo_utils.reflection to determine all the possible kwargs that can be
sent to TroveContext, some of which are consumed by TroveContext and
the rest of which are sent along to RequestContext().
The construct in the earlier _remove_incompatible_context_args() also
modified kwargs.keys() by pop'ing values from it while iterating over
this. Python 3 takes a dim view of this and therefore some changes
have been made to accomodate this.
A unittest has been added to ensure that the from_dict() method
properly dumps stuff it doesn't know about. The test explicitly
verifies the warning generated when a bogus argument is eliminated.
