67da8d8c31
Adds the capability to utilize the indirection API model. The vast majority of this change is the removal of legacy comments and the swap of decorators on object methods to allow the Versioned Objects Indirection API to route the calls upon objects through the RPC layer to the conductor. In order to make these calls occur, we need to also send along a context, which is required to call the RPC layer, which is fine. Original tests still work in that API surface calls still ultimately trigger DB API calls in the backend, thus test changes are actually minimal, similar to very slight changes in trait retrieval as well. In that we really can't nest objects across the indirection layer. Change-Id: Ia161fef67b8a116fdf7cad9b2e559ba75263e196 Signed-off-by: Julia Kreger <juliaashleykreger@gmail.com>
