Add the ability to sync kube config files (#2567)
* Add the ability to sync kube config files - Will update when the files changes - add KUBECONFIG_SYNC label - fix rebase and change to addObservableSource - move UI to user settings - support shallow folder watching - add some unit tests for the diff-er Signed-off-by: Sebastian Malton <sebastian@malton.name> * responding to review comments Signed-off-by: Sebastian Malton <sebastian@malton.name> * fix tests and add try/catch Signed-off-by: Sebastian Malton <sebastian@malton.name> * always sync c&p folder, remove bad rebase Signed-off-by: Sebastian Malton <sebastian@malton.name> * fix preferences Signed-off-by: Sebastian Malton <sebastian@malton.name> * Fix settings saving and catalog view Signed-off-by: Sebastian Malton <sebastian@malton.name> * fix unit tests Signed-off-by: Sebastian Malton <sebastian@malton.name> * fix synced clusters not connectable Signed-off-by: Sebastian Malton <sebastian@malton.name> * change to non-complete shallow watching Signed-off-by: Sebastian Malton <sebastian@malton.name> * fix sizing Signed-off-by: Sebastian Malton <sebastian@malton.name> * Catch readStream errors Signed-off-by: Sebastian Malton <sebastian@malton.name> * don't clear UserStore on non-existant preference field, fix unlinking not removing items from source Signed-off-by: Sebastian Malton <sebastian@malton.name> * change label to file Signed-off-by: Sebastian Malton <sebastian@malton.name>
