/** A map between Miniflux's input properties and our input properties when modifiying feeds

|

* - feed_url
|
|
* - username
|
|
* - password
|

* - fetch_via_proxy

* These either do not apply because we have no cache or proxy,

|
* or cannot be changed because feeds are deduplicated and changing
|
|
* how they are fetched is not practical with our implementation.
|
|
* The properties are still checked for type and syntactic validity

* invalid values.
