Add option for retry_servfail (#3247) (#3251)

* Add option for retry_servfail

cf. https://dnspython.readthedocs.io/en/latest/resolver-class.html#dns.resolver.Resolver.retry_servfail

Setting this option to `True` allows for the possibility of the lookup plugin to retry and thereby recover from potentially transient lookup failures, which would otherwise cause the task or play to bail with an unrecoverable exception.

* Create 3247-retry_servfail-for-dig

* documentation for `retry_servfail` option

* Rename 3247-retry_servfail-for-dig to 3247-retry_servfail-for-dig.yaml

* fix whitespace

* Update plugins/lookup/dig.py
