feat(op-deployer): add support for http locator (#13464)

* feat(op-deployer): add support for http locator

Given that the downloader code already supports it, we might as well offer the capability.

This is useful for pointing to local registries during development, without having to worry about SSL.

* update locator_test.go

http is now supported.
ftp can be used for unsupported scheme test.
