Mongo Collection and Index Creation

[kyleoneill]

When the database is initialized a check is made to verify that all indexes exist, if any are missing then they are created during initialization.

The code that does this is messy, difficult to read, not DRY, etc. and should be cleaned up and written in a more extensible fashion. Maybe macros/traits can be used to define indexes on the structs themselves?

Also included in this issue is checking if there is a better way to handle test db wiping in /testing/mod.rs

Also included in this issue is checking if there is a better way to handle mongo operations like find_one, as there is a lot of nearly duplicate code in the various model foo_db.rs files. I should have generic wrapper functions for things like find, find_one, insert_one, etc. which can be given filter/update documents and error handle.

Basically every db file is handling mongo differently (hence this issue and #38) but the newest one which is probably the one I should use to standardize the rest is message_db.rs.

This issue is now a general refactor for how mongo is handled (db operations, error handling, expanded error handling, index definition, collection name definition and access, etc).
