The cmake plugin creates multiple run configs

When opening a CMake project and selecting a kit, I've noticed that two run configs are created.

For developers, that's a bit of a confusing experience, as there is no indication as to which one to use. I would recommend to create only one that is specific to the Ubuntu cmake plugin.

I realise this is not trivial, but something it might be worth considering to provide a smooth developer experience. Here is an extract of the IRC conversation with zbenjamin about this subject:

<zbenjamin> dpm: every plugin in QtC can create its own runconfig, i can not interfere with that sadly :/
<dpm> zbenjamin, what does that mean? That one of the runconfigs is not valid? Which one should I use?
<zbenjamin> dpm: yes, thats the case, the problem is that cmakeplugin will automatically create a runconfig if the project creates a executable and the connected device is a linux device
<zbenjamin> dpm: the problem is first if i make cmakeplugin stop to create runconfigs it will break other projects taht use RemoteLinux devices but not our plugin
 dpm: cmakeplugin has no knowledge if a project is a ubuntu project or not
<zbenjamin> dpm: which one to choose is harder, maybe i should prefix it with ubuntu-<runconfigname>
<dpm> zbenjamin, rather than adding the prefix, is there a way to automatically select the right config?
<zbenjamin> dpm: i could use some trickery i gues
