Description of the change
Fixing potential controller environment exposure by removing some sprig template functions:
env,expandenv- controller environment variables exposure (which can contain sensitive data)getHostByName- add possibility to resolve dns entries from templates, which is not secure in some casesThis potential exposure is added by PR #1542 where security risks was described in "possible drawbacks" section.
Also, sprig func map is now initialized due module initialization and reusing for rendering, which may improve performance.
In fact is just port of the argocd solution, which described in initial PR #1542
