Add parameter to post feed endpoint

[himynamesdave]

I've noticed some RSS feeds link to other blogs in the <link> property

e.g.

Companies are becoming more resilient to attacks, and the ransom payments extorted from businesses by hackers are on a downward trend.

This is usually done when companies pay the blog to promote their own posts.

That said this is problematic for most of our use cases

To avoid this, we should add an option where the user can select to only download blog posts in the link that match the domain of the rss feed.

e.g. if feed is

https://grahamcluley.com/category/security-threats/ransomware-malware/feed/

then

<link>https://grahamcluley.com/smashing-security-podcast-378/</link> would be downloaded <link>https://www.tripwire.com/state-of-security/better-resilience-sees-more-extorted-companies-refuse-pay-their-ransomware</link> would not

add this as a setting in post feed

include_remote_blogs as a boolean (default is false). If set to true, will try and download remote sites.

Also include this data in any job run for this feed, so that user can remember if it was set or not when checking a job
