Implements a decorator using a context to handle operations inside a transaction.

Create a decorator like @transaction to handle operation that should ran into a transaction.

Example:

@transaction
def create_charge(self,**kwargs):
    # Doing some stuff

Behind the scenes the connection class should run:

connection.begin()
connection.query()
connection.commit()
connection.rollback()

In just one step or rollback all case something gets wrong.

Sure. This is really wrapper around what we already have so should be simple 👍
