[COMMON] Provide convenience templates for mariadb secrets
Usage of plain strings is very fragile especially when you try to change them. That's why instead of depending on strings let's just define a few convenience templates to be used in projects that use mariadb-galera chart. Issue-ID: OOM-2249 Change-Id: Ib867d34090b06a15ea3898a9524f5e3d04a656c0 Signed-off-by: Krzysztof Opasiak <k.opasiak@samsung.com>
