Fix TransactionContextWrapper limiter accounting

The fix for CONTROLLER-1814 wrecked the fragile OperationLimiter
accounting between TransactionContextWrapper and
RemoteTransactionContext. The problem is that during initial
connect time TransactionContextWrapper acquires limiter operations
and the state of the OperationLimiter is inherited by
RemoteTransactionContext. This though means that we need to know
which operation actually acquired a permit and which did not.

As it turns out, this needs to make TransactionContext methods take
an additional hint as to whether a limit attempt was made and what
was the result of it.

Furthermore the internal TransactionContextWrapper logic needs to
be changed from 'enqueue and wait' to 'wait and enqueue' strategy,
so when an operation is added to the queue and potentially picked
up by executePriorTransactionOperations() we already know whether
a permit was acquired or not.
