Index map description file (#9384)

Add scraping for map indexing to read 'description.html' file in map repos
and stores contents in database. When serving map listings the description
will be retrieved from database and sent to game client.

Game clients could very well download map description data when selecting
different maps. There is a pretty significant performance penalty to this
and having a larger one-time download to get all the data should have
better performance than downloading descriptions on-demand.
