kamal app logs: grep_options should be before grep pattern

[dougireton]

When running this command:

bundle exec kamal app logs -d staging --roles web --skip-timestamps --grep "Rails::HealthController" --grep-options "-v"

I get this error:

grep: grep_options: No such file or directory

Relevant Kamal code:

def logs(version: nil, since: nil, lines: nil, grep: nil, grep_options: nil)
  pipe \
    version ? container_id_for_version(version) : current_running_container_id,
    "xargs docker logs#{" --since #{since}" if since}#{" --tail #{lines}" if lines} 2>&1",
    ("grep '#{grep}'#{" #{grep_options}" if grep_options}" if grep)
end

grep_options should come before the grep pattern. Currently grep thinks the grep_options are a filename to search in.
