New tool: sync:keywords - synchronize composer.json keywords with github topics

[michalbundyra]

$ zf-maintainer sync:keywords <github-token> -o|--org=<org> -r|--repo=<repo-pattern> [--dry-run]

Replaces all github topics with keywords from composer.json file (master branch) for repositories matching provided pattern <repo-pattern> in provided organization <org>. <repo-pattern> can be alphanumeric string with dashes and * to match any part of the repository name.

Here we have --dry-run result for following command:

$ bin/zf-maintainer sync:keywords <TOKEN> --org=zendframework --repo=zend-expressive* --dry-run

On red we have marked topics to remove, cyan - keywords to add. In case we don't have any keywords in the composer.json there is an error message next to the repository name. Repositories are sorted by name, asc.

Resolves #35 /cc @Xerkus @froschdesign

I'd like to see one and/or both of the following changes:

• some verbiage in the help text indicating that a dry run SHOULD be run to determine if the repo keywords contain keywords not in the composer.json;
• or have it error if the repo HAS keywords, and one or more are NOT in the composer.json.

The reason is that there are a number or github keywords that are useful, but we may not be using in composer.json files yet.
