- execution_options() on Connection accepts

"isolation_level" argument, sets transaction isolation
level for that connection only until returned to the
connection pool, for thsoe backends which support it
(SQLite, Postgresql) [ticket:2001]
- disallow the option on Engine (use isolation_level to create_engine()),
Executable (we don't want to check/set per statement)
