[client] avoid circular deps in time-based flusher
The boost::bind() makes cast of parameters during the call,
not during creation of the functor object:

So, it's necessary to pass weak pointers to the background auto-flush
task to avoid circular dependencies between client::KuduSession::Data
and rpc::Messenger. Besides, it does not make much sense to store
shared reference to messenger in KuduSession::Data since it's always
passed as a weak reference and then promoting to a shared one during
the call in all usage scenarios.
Thanks to Adar and Todd spotting the usual suspect there.
This is a follow-up for 93be1310d227cf05025864654ca3f6713c2ddc2c.
