OF-2368: Register MUC ping responses as user activity
Previously, Openfire was sending an IQ Ping to inactive users, but didn't register the response as activity.
OF-2371: Increase queue capacity for OutgoingSessionPromise
The queue should be large enough to easily hold the stanzas sent back to a federated user that is joining a MUC room.
OF-2369: Do not do outbound S2S when inbound disabled.
When Openfire is configured to not allow inbound S2S of a particular flavor (direct or non-direct TLS) do not try to establish outbound S2S of the same type.
This effectively makes an outbound S2S attempt impossible when Openfire is configured to not accept any inbound S2S.
