swarm, cmd/swarm: Merge branch 'master' into multiple-ens-endpoints

Browse Source 
Merge with changes that implement config file PR #15548.

Field *EnsApi string* in swarm/api.Config is replaced with
*EnsAPIs []string*.

A new field *EnsDisabled bool* is added to swarm/api.Config for
easy way to disable ENS resolving with config file.

Signature of function swarm.NewSwarm is changed and simplified.
