[User story] Post tags

[alexkisielewicz]

As a user, I can add tags to the posts and view the list of the posts associated with specific tags, so I can browse posts that I am interested in.

Acceptance Criteria:

• Tag field is present in add post form.
• User can add multiple tags, separated with commas.
• Tags belonging to specific posts are displayed in this post detailed view.
• User can click on a tag and get redirected to a filtered post list view with posts marked with this tag.

Adding tags is possible in the form when adding new posts and tags are displayed in the UI, however, they are not yet clickable and the user cannot be redirected to the filtered view. The back-end application needs to be adjusted accordingly. This has been marked as a possible future enhancement feature and could be developed further.
