MySQL integration: run the full setup

[mtojek]

Run the agent code, select MySQL integration to install and test it.

First spotting: to build an agent, I need to install full Xcode (xcodebuild) and to do that, I need to upgrade Mac OSX.

Wow, I didn't expect this. Which OS X version are you on?

@michalpristas Where are we standing with having an easy test setup available? Also we should find a way that users don't have to run the full packaging to just use the agent binary.

@mtojek I hope as soon as we have snapshot builds available, all this becomes obsolete. Perhaps as an intermediary solution, we could just have link to a current binary we keep updating?

@ruflin in PR here: elastic/beats#17312

[michalpristas]

agent binary is fine but we still need correct beats to work properly, the thing in PR is a limited version of packaging which builds only linux bits and has a check for existing image in image to speed it up
