Add support for pod level security context configuration in operator chart #817
Description
According to the CIS Kubernetes Benchmark, security context should be set at pod AND container level: https://www.tenable.com/audits/items/CIS_Kubernetes_v1.5.1_Level_2.audit:b9a496f0341d9fc80d9c5cc954db46a7
Right now the operator chart only supports setting the security context at container level.
Please add support for pod level security context configuration to the operator chart.
