snapshot:: .snaps already present before uss is enabled
Test Cases in this module tests the USS where .snaps folder is already created and checks for behaviour before enabling uss and after disabling uss Change-Id: I9c6dcca1198b7fed37103cc21f3ecba72bfa20a5 Signed-off-by: srivickynesh <sselvan@redhat.com>
