(instead of using the id from broadcast_event)
we need every XML blob we send to have a different ID. if we're sending
different XML blobs for each provider, then each one should have a
different identifier. So, instead of taking the identifier from the
broadcast_event, take it from the broadcast_provider_message instead.
Note: We're still going to the broadcast_event for most fields, to
ensure they stay consistent between different providers. The last thing
we want is for different phone networks to get different content
A BroadcastEvent knows when an event was sent and should expire
We pass through these values directly to the CBC Proxy, because
BroadcastEvent knows how they should be formatted

"areas" and "simple_polygons" in "transmitted_areas" do not have the
same length
as an example, choosing the area "england" results in a single item in
"areas" but many polygons in "simple_polygons"
therefore zipping these two together gives a list of areas:
* of length 1
* containing only new grimsby
which is not what we want
as the CBC does not care about the areaDesc field within CAP, we should
omit it from the function invocation and delegate the contents of
areaDesc to the CBC Proxy implementation

We are phasing out our cbc-proxy stub which displayed CAP XML messages
We are in the process of testing with real CBCs, so maintaining our own
stub is not useful
This commit
* removes the HTTP POST requests to the CBC proxy
* writes up the update/cancel methods of the cbc_client (not impl)

When we create a broadcast message, we should invoke the cbc proxy to
send a cap message
Either a function will be invoked within AWS, or a noop function call
is made, depending on the environment
We have only implemented CB message creation in the CBC Proxy, without
polygons, therefore we:
* only invoke the CBC Proxy during message creation
* only send description, identifier, and hard-coded headline

It is not of the form
[[lat, long][lat, long]] as this would only hold a single polygon. It
instead needs to handle multiple polygons so instead is of the form
[[[lat, long][lat, long]]].
use the new endpoint from cbc proxy. create a new task that just
serializes the event and sends it across rather than sending a template
and the broadcast message.
some changes to serialize to make it json friendly etc. it also expects
sent_at and transmitted_finishes_at to always be set (we set them in the
code but don't enforce it n the DB right now), as they're required by
utils template. not sure whether we'll update db constraints to be more
strict or utils template to be more permissive just yet, wait until we
find out more about the requirements of the CBCs we integrate with.
task takes a brodcast_message_id, and makes a post to the cbc-proxy
for now, hardcode the url to the notify stub. the stub requires template
as the admin/api get it, so use the marshmallow schema to json dump it.
Note - this also required us to tweak the BroadcastMessage.serialize
function so that it converts uuids in to ids - flask's jsonify function
does that for free but requests.post doesn't sadly.
if the request fails (either 4xx or 5xx) just raise an exception and let
it bubble up for now - in the future we'll add retry logic
