Fix some RedisLocks auto-releasing too fast

[ClearlyClaire]

Fixes #16238 #15645

By default, RedisLock expires after 10 seconds, which may not be enough to process statuses, especially when those have attached media files.

This commit extends those 10 seconds to 15 minutes, which should be plenty enough to handle any status, while being short enough to not waste many sidekiq job retries in the exceedingly rare case in which a sidekiq process would crash when processing a Create or Delete.

I think this may also close #15645

Only partially, there are many other uses of RedisLock, I will look into them shortly.

Pushed a commit changing other RedisLock timeouts, basically the numbers I chose are:

• default of 10 seconds for anything doing only a handful simple database queries
• 5 minutes for anything performing significantly more involved queries (e.g. going through lists of followers and pushing redis messages)
• 15 minutes for anything making HTTP requests to third-party servers

Note than in most cases having a long timeout isn't an issue. It's only an issue if the sidekiq process crashes abruptly (normal exception handling will make sure the locks are released) or the redis process crashes. Still, we should probably avoid having very long timeouts to make sure recovering from such a crash doesn't end up being a big issue.

It seems to be happened again.
