Feature | Adds command to open the cmake cache file

The Feature

Adds a new command to open the cmake cache file. CLion has this functionality which I always found super helpful.

Considerations

In this initial implementation the file is opened simply with a vim edit <cache file> command. Being a vim classicist this suites my workflow, but I can see that other commands (for example CMakeOpenRunner) open a new split window. Would this be preferable?

Thanks for your contribution!
Personally, I never used the cache file that much - except for skimming trough it.
What is your way of working with that file?
Opening it in the current buffer might be a legitimate approach for frequent edits.
If you only want to have a glance at it or make a quick one-line edit, opening it in a floating window (like CMakeSettings does) might also be worth a consideration.

I think I wouldn't make it open in a split like the runner/executer. They are kinda terminal-like instances for an ongoing process.

WDYT @Civitasv?

What is your way of working with that file?

I'm often editing the cache file to switch on and off the various configuration options a project might expose during development. After editing cmake is smart enough to detect the change and regenerate the next time a build is kicked off.

I think it's okay to open it in current buffer.
