[infra][neutron] Requesting help to remove feature branches

Dear Infra Team,

We have decided to remove from the Neutron repo the following feature branches:

feature/graphql feature/lbaasv2 feature/pecan feature/qos

We don't need to preserve any state from these branches. In the case of the first one, no code was merged. The work in the other three branches is already merged into master.

Best regards

Miguel
