Add Osmose Q/A layer

[bhousel]

Following #5201 - we can add a Q/A layer for Osmose

Some information about the ruleset and API can be found on the osm wiki.

The list of checks that Osmose performs is here - we'll want to support a reasonable subset of these.

Similar to KeepRight, we can just pick a single marker style and a few colors to differentiate, rather than trying to match the literal osmose icons, which don't seem to mean anything.

Osmose API is quite nice as it directly provides array of element IDs related to the error unlike KeepRight. See "elems" key.

Full error detail is not provided (by default) when fetching errors from /errors unless full=true parameter is specified in the query. Unsure whether implementation would want to fetch specific error detail separately when an error is interacted via /error/ID as a means to reduce the amount of data transfer or if that's not a big deal.

Just some food for though, I've messed around with my own half-baked implementation of this in the past, but I'm mostly commenting so this appears in my participating notifications 😛
