Re-order template keywords

[MoonMoon2]

Issue was because YAML output for this section of the cluster.yaml was

parameters: parameters: {} pg_hba: [] pg_indent: []

Whereas it should be

parameters: {} pg_hba: {} pg_indent: {}

but parameters is a helm keyword so it would consume all the keywords in the parameters step before pg_hba or pg_indent were called.

This simple re-ordering should fix the issue (and has for me in testing)
