Staging 3.6.0 and camel master

[oscerd]

Preparing for 0.6.0 release:

• This rebase master on camel-master, so we'll have a lot on new features and improvements
• Align to 3.6.0 staging
• We just need to remove the staging repositories once 3.6.0 will be released and will be ready to go
• I'll update camel-master to point to 3.7.0-SNAPSHOT

Lets have this as draft, once ready I'll remove the staging repo and we can merge.

We are releasing 3.6.0, so we can simply remove the staging once ready.
