Add log file analysis to the app#252

Create ability to connect log files to Site Audit to get insights about which landing pages aren’t crawled by search engine bots, which of them are the most popular in crawling etc.

This tool deserves to be the separate tool (like Site Audit, Rank Tracker etc.) and also to be implemented inside the Dashboard, Site Audit etc.

You also can create such Extra tool for a one-time log file analysis, not continous monitoring.
