Support array of values with etc/*.config files

Need support to use array of values property in configuratuon file (*.cfg)

When trying to use configuration file to persist OSGi configuration in Karaf 3.0.0, there is an issue when using property with array of values. My configuration file is placed in /etc folder and looks something like this:

property = ["value1","value2"]

The problem is that array does not get interpreted properly, so in Web Console I see one string value instead of array of values. I figure out that if I use .config as extension for the configuration file, the array gets interpreted properly, but I experience another issue then, like for example that my config file gets overwritten. It seems there is no support for arrays in configration file with file extension .cfg
