Instead of returning an HTTP 200 and a `volumeAttachment` object, attaching a volume to an instance returns HTTP 202 starting from API version 2.101. To keep the functionality for older API versions, we move the `_attach_volume()` method from n-api to n-conductor and either do a call or a cast depending on whether the API needs to return a value. n-conductor then handles reserving the block_device_mapping's device by calling n-compute before it starts the previously-already-async volume attachment. We have to move `_check_attach_and_reserve_volume` into compute utils, because it's getting called in both conductor and compute api (for the shelved offloaded attach). The new RPC method in the conductor needs a long timeout when used with API versions less than the new 2.101, because it waits for the call to `reserve_block_device_name()` in nova-compute which already needs a long timeout. Updating the functional tests' `post_server_volume()` and `_attach_volume()` to not return the attachment anymore is possible, as no test uses the returned values.
