Add database tag to DefaultMongoCommandTagsProvider

[nathankooij]

The MongoDB Java driver added the databaseName field to commands in 4.11. We can expose this via the DefaultMongoCommandTagsProvider. While there, I've also replaced usage of deprecated constructors.

I see the builds fail on some deprecation warnings in unrelated code. What is the recommended approach for moving forward here?

Thank you for the PR!

The build is not failing because of deprecation warnings, the build fails on errors:

1 error
8 warnings

Those 8 warnings do not make the build fail, that 1 error does:

/home/circleci/micrometer/docs/src/test/java/io/micrometer/docs/observation/ObservationInstrumentingTests.java:463: error: incompatible types: try-with-resources not applicable to variable type
        try (Javalin javalin = Javalin.create().before("/hello/{name}", ctx -> {
                     ^
    (Javalin cannot be converted to AutoCloseable)

This still seems to be unrelated to your changes and if this is failing, main should too, I'm checking it.

[jonatan-ivanov]

Should be fixed (see #4299), could you please rebase your changes on main?

Thanks for pointing out & fixing the issue. I've rebased my branch.

@nathankooij Thank you for the contribution. It will be in the upcoming 1.13.0-M1 milestone release.

It seems that "database" tag should have been added through #2932, #3069, and 8d9db81. The release note for 1.10.0-M1 contains the entry, but v1.10.0-M1 tag itself doesn't contain the changes. Given that #3069 had the "2.0.0-M4" milestone, it seems to have been lost when changing from 2.x to 1.x.
