k8s: Resolve Docker response formatting issue
Checker collects information on cluster by Docker queries: $ docker ps ARGS... # Casablanca $ docker inspect ARGS... # Dublin Arrays of values are then filtered from those. They include: * opening bracket ('['), * closing bracket (']'), * new line. Additional characters affect check results if last flag (including "]\n") requires specific value. Issue-ID: SECCOM-235 Change-Id: I6838342b7e2ecdc44a47ffe02286266003e0b4d3 Signed-off-by: Pawel Wieczorek <p.wieczorek2@samsung.com>
