Client API change: Centralize access to subscription status, better control of acquire/accept.

client/AckPolicy: removed, functionality moved to Subscription and SubscriptionSettings
client/SubscriptionSettings: struct aggregates flow control & accept-acquire parameters for subscribe.
client/Subscription: represents active subscription. Query settings, unacked messages, manual accept/acquire
client/SubscriptionManager: use AcceptMode, AcquireMode enums rather than confusing bools.

Issues addressed by the change:
 - old use of bool for acceptMode was inverted wrt AMQP enum values, bools are confusing.
 - old AckPolicy was broken - not possible to access the instance associated with an active subscription
 - old AckPolicy did not provide a way to do manual acquire, only accept.
 - setting values on SubscriptionManager to apply to subsequent subscriptions is awkward & error-prone, now can use SubscriptionSettings to control on each subscribe individually.
 - a subscription is a central concept in AMQP, it deserves to be a class. Subscription and SubscriptionSettings provides a single point for future expansion of interactions with a a Subscription.
