[COMMON] Create templates for services and PV
Proposition of common templates to make service declaration and PV declaration consistent accross OOM. Propositions of templates for sub parties of resource definitions such as metadatas, selector and containerPorts. I've also made an example with cassandra. Change-Id: I8b8aa8eb61dafba75e89add1979114a0eefce243 Issue-ID: OOM-1971 Signed-off-by: Sylvain Desbureaux <sylvain.desbureaux@orange.com>
