Michael Holloway 3513c642dd Create push subscription manager group/right to clean up dead subs
Creates a new push-subscription-manager group and an associated
right, manage-all-push-subscriptions. The purpose of this is to
allow privileged accounts to purge expired subscriptions from the
database on behalf of other users. A user with this right will be
permitted to delete any subscription from the DB based on the token
alone. For all other users, deletion requests will be limited to
those associated with the requesting user's central ID.

This right will be granted to a bot account on Metawiki associated
with the Wikimedia push notifications service, and the push
notifications service account will make push subscription delete
requests to the API for subscriptions for which vendor APIs return bad
subscription responses.

Additionally, the providertoken parameter to ApiPushSubscriptionDelete
is updated to allow multiple providertoken values.

Mateus Santos c188dac23f push: send apns topic when present
1) send apns topic when present in subscription metadata
2) check if subscription metadata is a valid JSON string
3) make epp_id column at echo_push_provider table auto_increment,
otherwise it will fail when trying to add a second row in the table

Michael Holloway 15d48278be Create and enforce a config setting for max subscriptions per user
Creates a EchoPushMaxSubscriptionsPerUser config setting (default: 0)
that controls the maximum number of subscriptions a user may associate
with the user's central user ID.

The setting is enforced in EchoPush\SubscriptionManager::create().

To allow creating push subscriptions for development, set
$wgEchoPushMaxSubscriptionsPerUser to a positive integer value in
LocalSettings.php:

 $wgEchoPushMaxSubscriptionsPerUser = 10;

Michael Holloway c9a826190d Remove overbroad DB error catching in ApiEchoPushSubscriptionsCreate
Rather than catching all DB errors (and assuming they are duplicate
entry errors), ignore duplicate entry errors and use affectedRows() to
determine whether the subscription already existed.

Michael Holloway a3674974f1 Add push subscription management
Adds DB tables for storing push subscriptions, some DB interaction code
for retrieving them within MediaWiki, and a set of API modules for
managing them from the outside world.

When testing this patch, be sure to run maintenance/update.php to create
the new tables, and set $wgEchoEnablePush = true in LocalSettings.php
to enable the API new API module.

N.B. The current DB schema is centered on app push subscriptions. Web
push subscriptions require slightly different handling, since they are
provided by browsers as a JSON blob rather than a token string. How to
handle web push subscriptions is a question we can defer until the time
comes to add web push support.

Subscription data is stored in the echo_push_subscription table, with
provider names normalized into the echo_push_provider table. We expect to
be looking up subscriptions by central user ID, so that column is indexed.
The subscription data also includes a column to store SHA256 digests of
the subscriber tokens. This is for use as a unique key constraint, since
we expect every push token to be univerally unique, and the token values
themselves may be too large to reasonably index in MySQL.
