Rename light::request::Requests to Batch

[rphmeier]

...and move it and the builder into a "batch" module.

"Batch" conveys the role of the structure w.r.t. partially handling responses much better.

This issue is labelled with annoyance: The client behaves within expectations, however this "expected behaviour" itself is at issue. It's neither assigned nor linked to any milestone.

@paritytech/core-devs Please decide on a deadline and add an assignee within 7 days, thanks!

Interested in taking this. Should RequestBuilder become BatchBuilder?

Also, where should the newly created batch module live?

[rphmeier]

@asymmetric it could just be called Builder since it can be referenced with batch::Builder. The batch module should live where the "builder" module does now, so essentially just a file and type rename.

I'm working on this so I'd be happy to be assigned :)

thanks and noted, but unfortunately we can't assign issues to people outside the organization :(
