Combine console logs pages

[tlmii]

Resolves #176

After #987, merging the logs pages is the next logical step.

• Removed the Project Logs, Container Logs and Executable Logs pages
• Created a new Console Logs page
• Changed the menu to have a Monitoring section that has Console logs, Structured Logs, Traces and Metrics under it and removed the old Logs section that had all of the console logs and structured logs
• Removed some commented code from the menu that should have been removed earlier

Unlike #987, not much to show from a visuals perspective other than the changes to the menu structure:

Note: #176 had discussion of indicating the type of resource that is selected. For the moment, I've left that out of this PR and plan to do follow up once people take a look and we can agree on a design (icon in select? text in the header?).

I think this is fine as it pretty much matches structured logs.

The monitoring pages show resources ordered alphabetically. The resources page orders them by type, then alphabetically. How do we feel about that consistency?

I'm conflicted about it (don't like the inconsistency) but it was done on purpose:

For the resources page, with the new columns whose data vary by type, grouping the rows by type helped visual scanning (imo at least) - when the columns with different data in them were intermingled it felt harder to scan them.

For the monitoring pages, without any extra data to identify why they were not alphabetical (in other words no type column or icon) it felt more natural to be alphabetical.

I'll readily admit these are subjective takes and am happy to tweak or take feedback. But that's why I went that way after fiddling with a few variants.

When you click on the console logs link in the menu, what decides which app to display?

Structured logs and traces have an "All" option and select it by default. But that doesn't make sense for console logs.
Metrics doesn't display anything by default and prompts you to choose a service (note: service should be renamed to resource)

I think the console logs could do the same thing. That page would also be displayed if a bad name is in the url, e.g. http://localhost:15888/ConsoleLogs/ThisDoesntExist

@JamesNK This PR didn't change the way that worked from before - it selects the first one in the list (which is sorted alphabetically). I think this is a good suggestion though. I filed #1055 to track it.
