We need to consider the case where the database name is defined in the url, for example mongodb://localhost:27017/my_test_db.
In that situation, we should just show table names.
We already do similar thing for mysql/mariadb here. We can convert that to a hash map and consider mongodb and mongodb+srv as part of that.

I added this myself to see how it looks, and noticed that table names in drawer got db. prepended, like db.users. We can probably solve that in the schemes_tables_query somehow.

let s:mongodb_tables_query = 'db.adminCommand("listDatabases").databases.flatMap(d => {use(d.name); return db.getCollectionNames().map(c => [d.name, c].join(","))}).join("\n")'
