Add Blog Post Migration

kbentham → changed the visibility of the branch 3469272-blog-post to hidden.

I tested the changes but no data for the files was migrated. Is this expected?

$ drush migrate:import drupalorg_migrate_blog_post_files
 [notice] Processed 0 items (0 created, 0 updated, 0 failed, 0 ignored) - done with 'drupalorg_migrate_blog_post_files'
$ drush migrate:import drupalorg_migrate_blog_post_media_documents
 [notice] Processed 0 items (0 created, 0 updated, 0 failed, 0 ignored) - done with 'drupalorg_migrate_blog_post_media_documents'
$ drush migrate:import drupalorg_migrate_blog_post_media_images
 [notice] Processed 0 items (0 created, 0 updated, 0 failed, 0 ignored) - done with 'drupalorg_migrate_blog_post_media_images'

I do get data for the blog posts:

$ drush migrate:import drupalorg_migrate_post
 538/964 [===============>------------]  55%

I merged the changes and renamed a couple of small things, so if there are any further changes needed, please open a new MR.

It actually ran in the very first time, so the output there was the second run, where the 0/0/0/0 is expected if there isn't anything new.
Fixed. Thanks!
