`gcovrs`'s `config` option not applied through `Ceedling`s' default options

[swaldhoer]

We are using the config_file option of the gcovr plugin.
This means, that we only set in our project.yml:

:gcov:
  :utilities:
    - gcovr
  :gcovr:
    :report_root: "../../"
    :config_file: ../../foo.cfg"

The problem is now, that Ceedling still provides default values if these are not specified, e.g., for --exclude on the command line and these have precedence over the configuration file:

Ceedling/plugins/gcov/lib/gcovr_reportinator.rb

Lines 129 to 148 in c50ff9d

	args += "--exclude-throw-branches " if gcovr_opts[:exclude_throw_branches]

	args += "--gcov-ignore-parse-errors " if gcovr_opts[:gcov_ignore_parse_errors]
	args += "--keep " if gcovr_opts[:keep]
	args += "--delete " if gcovr_opts[:delete]
	args += "-j #{gcovr_opts[:threads]} " if !(gcovr_opts[:threads].nil?) && (gcovr_opts[:threads].is_a? Integer)

This is of course undesired behavior when a configuration file is used.

So, when :config_file: is provided, all other options shall not be set to default.

Important: As Ceedling is the setting the cwd implicitly through where it is invoked, :report_root: must still be parsed nevertheless!
