feature idea - transaction panel

[jvanasco]

opening for discussion...

a panel that shows data about the pyramid_tm transaction manager could be useful when debugging. i'm not sure how much of this data is potentially available:

• transaction status (commit, abort, etc)
• who joined (even the object classes are useful, ie there may be a sqlalchemy, a sendmail, a celery)
• who voted what (I don't think this is trackable)

anything else?

I have placed the toolbar explicitly OVER pyramid_tm and so a panel should be able to observe the entire lifecycle of a transaction if it wishes. It would want to hook request.tm to monitor what happens.
