[UA] Facilitate batch reindex command to user

[sabarasaba]

Summary

This PR adds support for bulk selecting ES deprecations and show a console command to reindex them.

How to test

• Follow the instructions in https://github.com/elastic/kibana-team/issues/1521. Use the data folder starting with [01] because it has the largest variety of deprecations.
• Start kibana with the changes of this pr checked out
• Verify that in UA -> ES Deprecations you can select multiple issues and if they are of the reindex type a CTA should appear that allows you to run the command in console.

No strong feeling on my comments. I figure we may want to add just a bit more context to the modal, maybe?

Thank you for working on that @sabarasaba!! I've done some manual testing and I don't think we should allow users to select indices that are already reindexed or in progress, what do you think?

Apart from that, everything looks good to me. It has been so nice to reindex 34 indices with just 4 total clicks! 😻

That's a very good and valid point, thanks for bringing that up! I've fixed that with 770829b

I let you a nitpick comment, but I tested locally and it looks good to me :)
