Un-negate the names

[ppalaga]

We have several config options which start with disable as well as some similarly named classes. Using negation in names makes them harder to understand, mainly when get negated once again in an expression like the following.

@BuildStep(onlyIfNot = Flags.MainDisabled.class)

I propose to rename all those to something like quarkus.camel.main-enabled and refactor all as needed. We should do this before 1.0.0.

Please assign to me.

This would be easy to do and I am ready to do that. If somebody wants to veto the proposal please do so sooner rather than later so that I do not waste my time.
