support multiple executables?

[jonboulle]

goaci currently only supports a single package and a single executable (that which gets produced by go get <package>). Should we consider adding support for multiple packages/executables? What would this look like?

I don't think supporting multiple executables in one go is sensible - it complicates things too much. My idea is as follows (and I already implemented it, so a PR is coming soon):

My assumption is that go get example.com/foo/bar will produce exactly one binary. This assumption does not hold for go get example/foo/bar/... where several binaries might be built.

For the former, goaci creates bar.aci with example.com/foo/bar as a name in manifest and with whatever binary go get buiilds.

For the latter, user has to use --use-binary option to select which binary should be put into image. Assuming that user passed --use-binary quux the result of goaci would be bar-quux.aci with example.com/foo/bar-quux as a name in manifest and with quux binary.
