Deploy guage on pool deploy

[martinkrung]

As the gauge deployer address = manager is the only one who can set token and distributor, if somebody outside is deploying the gauge, pool need to be deployed. On L2 deployment is almost free and has been available in the front end for some time , so this happens

We had this situation several times:

• it generates FE pollution (on re-deploy)
• it generates support request

solution: on deploy of the pool we should also deploy the gauge!
