[SuggestionProvider] Suggest investigating remote cache misses

[saraadams]

If remote caching is used and there are remote cache misses, suggest investigating the misses with a link to Bazel documentation.

Contributes to #90

Example output:

Suggestion: "Investigate remote cache misses"
The following actions with cache misses took the longest to execute:

Check https://bazel.build/remote/cache-remote#troubleshooting-cache-hits to learn more about how to debug remote cache misses. Increasing the cache hit rate can significantly speed up builds.
Caveats
- Only the first 5 of 6125 cache misses are listed. Try running this tool with --verbose to get more data.

Could you rebase on main and force-push please?

Suggested change

	public class BazelEventsUtil {
	public final class BazelEventsUtil {

...because this is a utility class with a private ctor, so I reckon we don't mean to subclass it.

[saraadams]

I think you only saw that file, because I hadn't rebased to main yet.

[saraadams]

Rebased and addressed TODOs. PTAL.

Caveats
- The profile does not include which target each action was processed for, although that data can help with investigating remote cache misses. It is added to the profile by using the Bazel flag `--experimental_profile_include_target_label`.
