acceptable
schemes as defaults

== The problem ==
There are defined only four schemes as default: http,https,ftp,ftps.
But URL can have many many more valid schemes.
HTTP and FTP as good defaults are invalid - they are too limited.
There is no simple way to extend these schemes nor disable scheme
validation.
We must extend URLField and redeclare `default_validators` class property,
which is too complex for that simple case.
== Possible solutions ==
- disable scheme validation and enable it only when user defines
`allowed_schemes` directly in URLField (backward incompatible)
- provide `allowed_schemes` as an optional argument for URLField
`init()`
- provide all valid schemes as default set (based on
https://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml)
== Preffered solution ==
Probide all (IANA) valid schemes as default together with possibility to
change them by URLField `init()`.
