 remote: add file uploads to repository_ctx.execute

This change adds file uploads to repository_ctx.execute when used with
--experimental_repo_remote_exec and remote execution. When passing a
Label as an argument the respective file is uploaded and added as an
input to the remote action. The Label argument is converted to the
remote path of the file. Labels in the main workspace are translated
to their workspace relative part. Labels in external repositories are
translated to paths starting with external/<repo_name>/....

Example:

repository_ctx.execute([Label("//config:find_config.py"),
Label("@foo_repo//config:options.json"), "foo"])

This will upload both find_config.py and options.json and stage them on
the remote machine at

./config/find_config.py
./external/foo_repo/config/options.json

and execute the command "./config/find_config.py
./external/foo_repo/config/options.json foo" on the remote machine. For
local execution the paths will refer to machines.
