Move experimental.pm to upstream=blead

[Leont]

Experience has thought that almost all changes to experimental.pm come from core, hence it's easier for maintenance if we move its upstream to blead, and sync the CPAN version with that.

• This set of changes does not require a perldelta entry.

I think that anything living in dist should have all of its files needed for a CPAN release in core. This is missing the Changes file and any tooling for producing a tarball.

With just this PR, maintenance becomes more painful. To make a release you need to find the appropriate repository outside core, sync the files from core into it, remove the version number from the core (since it isn't expected by the Dist::Zilla tooling) then make a release from there.

Yeah that is a bit challenging with the Dist::Zilla setup I'm currently using.

Yeah that's why such modules really should live in something like Dual-Life IMNSHO.

No actually dzil can handle that fine if you tell it to.
