[Toaster] review request for counters for filters

[Ravi Chintakunta]

I have pushed the implementation for adding counters to filters 

https://bugzilla.yoctoproject.org/show_bug.cgi?id=5821

to my branch: ravi/bug-fixes

http://git.yoctoproject.org/cgit/cgit.cgi/poky-contrib/commit/?h=ravi/bug-fixes&id=6da9e0124b2e749755714d8d8320cfd3d7884f5c

Please note that the counts for the filters in config variables is not adding up to the total count. Looks like there are config variables that are set in other files and that are not displayed as filter option.

Thanks,
Ravi
