Vlad Zolotarov 0689843e79 tracing::trace_state: add method to set the session's "params" map entries ...

Sometimes we want to be able to set "params" map after we
started a tracing session, e.g. when the parameters values,
like a consistency level parsed from the "options" part of a binary frame,
are available only after some heavy part of a flow we would like
to trace.

This patch includes the following changes:

   - No longer pass a map to the begin().
   - Limit the parameters to the known set.
   - Define a method to set each such parameter and save its
     value till the final sstring->sstring map is created.
   - Construct the final sstring->sstring map in the destructor of the trace_state
     object in order to defer all the formatting to be after the traced flow.
