Rename tests/kuadrant to tests/singlecluster

[pehala]

Since we now have multicluster tests, it makes sense to rename our current kuadrant tests to singlecluster

My idea is to name this single (tests/single) and multi (tests/multi) respectively.
WDYT @azgabur @averevki

Yeah I agree with Jakub, if we are already renaming, we can rename the modules to shorter names of single and multi. I dont think any meaning will get lost.

I like singlecluster and multicluster better. If I see testsuite for the first time without any knowledge about it, I wouldn't know what it's mean

[jsmolar]

singlecluster and multicluster it is. @averevki had a good point.
