store /search command in mongo db

[ThomasWu931]

Problem

We want the /search command to be recorded into the mongoldb client.

Solution

Following the current convention for slash_remove and slash_delete, we add the @log_command decorator to slash_search. Now log_command is called to manage search commands.

Next Steps

Since log_command decorator is used, this means that log_command is called prior to DiscordFS.locate. This means that ctx.defer(hidden=kwargs.get("dm", False)) is called after the slash command has been saved to the data base by log_command. This can be an issue if log_command takes too long which will raise a time out error by the discord api (Top answer here).

TLDR: Defering the msg should be called first before we store the command or anything else.

Sounds good - we've refactored a lot of the metrics logging to the discord server itself (no more space in mongodb, but mongodb is better to store more information).
