Feature Request: Pass in array of excluded methods in Markdown.random

[cameronbroe]

Basically, it would be nice to optionally pass in an array of excluded Markdown methods when calling Faker::Markdown.random so that you can selectively choose what you are randomly getting. I would be willing to submit a PR for this if it is something the community would like.

An example of how it could work would be with a call like this:
Faker::Markdown.random(exclude: [:headers])

Which will perform the random method, but never generate a header. This feature could allow for generating fake blog articles that add headers selectively, but still easily allow adding other elements between Faker::Lorem and Faker::Markdown to make the fake blog articles seem more realistic instead of potentially having 4 sets of headers and no real content between the headers.

I think I got this working for the random method but if you have good ideas about how to test it, I am all ears!

I think it might be cool to solve this problem a different way with what I will call a markdown sandwich (inspired by the s*** sandwich criticism technique). So you can use Markdown.sandwich(5) and you get:

• header
• 5 sentence lorem ipsum paragraph
• random markdown element

so it looks like a real blog post.

Markdown.sandwich(6,3) should produce

• header
• 6 sentence lorem paragraph
• random markdown
• 6 sentence lorem paragraph
• random markdown
• 6 sentence lorem paragraph
• random markdown

...so a pair of lorem-markdown content repeats 3 times (2nd arg) for longer form stuff.

Here's my PR 1064.
