  Given a deploy command, e.g. `gcloud app deploy ./dir other/service.yaml
  cron.yaml WEB-INF/appengine-web.xml`, the deployables can be on multiple
  forms. This method pre-processes and infers yaml descriptors from the
  various formats accepted. The rules are as following:

  This function is a context manager, and should be used in conjunction with
  the `with` keyword.

  1. If `args` is an empty list, add the current directory to it.
  2. For each arg:
    - If arg refers to a config file, add it to the configs set.
    - Else match the arg against the path matchers. The first match will win.
      The match will be added to the services set. Matchers may run staging.

  Args:
    args: List[str], positional args as given on the command-line.
    stager: staging.Stager, stager that will be invoked on sources that have
        entries in the stager's registry.
    path_matchers: List[Function], list of functions on the form
        fn(path, stager) ordered by descending precedence, where fn returns
        a Service or None if no match.

  Raises:
    FileNotFoundError: One or more argument does not point to an existing file
        or directory.
    UnknownSourceError: Could not infer a config or service from an arg.
    DuplicateConfigError: Two or more config files have the same type.
    DuplicateServiceError: Two or more services have the same service id.

  Returns:
    Tuple[List[Service], List[ConfigYamlInfo]], lists of deployable services

  This method uses several implementations based on the provided runtime and
  env. The rules are as follows, in decreasing priority:
  1) For some runtimes/envs (i.e. those defined in _GCLOUDIGNORE_REGISTRY), we
     completely ignore skip_files and generate a runtime-specific .gcloudignore
     if one is not present, or use the existing .gcloudignore.
  2) For all other runtimes/envs, we:
    2a) If ignore_file is not none, use custom ignore_file to skip files. If the
        specified file does not exist, raise error. We also raise an error if
        the user has both ignore file and explicit skip_files defined.
    2b) If user does not specify ignore_file, check for an existing
        .gcloudignore and use that if one exists. We also raise an error if
        the user has both a .gcloudignore file and explicit skip_files defined.
    2c) If there is no .gcloudignore, we use the provided skip_files.

  Args:
    upload_dir: str, path to upload directory, the files to be uploaded.
    skip_files_regex: str, skip_files to use if necessary - see above rules for
      when this could happen. This can be either the user's explicit skip_files
      as defined in their app.yaml or the default skip_files we implicitly
      provide if they didn't define any.
    has_explicit_skip_files: bool, indicating whether skip_files_regex was
      explicitly defined by the user
    runtime: str, runtime as defined in app.yaml
    environment: env.Environment enum
    source_dir: str, path to original source directory, for writing generated
      files. May be the same as upload_dir.
    ignore_file: custom ignore_file name.
              Override .gcloudignore file to customize files to be skipped.

  Raises:
    SkipFilesError: if you are using a runtime that no longer supports
      skip_files (such as those defined in _GCLOUDIGNORE_REGISTRY), or if using
      a runtime that still supports skip_files, but both skip_files and
      a. gcloudignore file are present.
