Using sprig with confd

[jcheroske]

Is there a straightforward way to have the sprig library available to my templates?

Sprig would provide some welcomed relief. There are a number of problems that can't presently be solved in confd because it is not yet based on Go 1.11 Templates, and therefore cannot perform variable replacement, to achieve things such as string contains, array contains, etc.

{{$arrayContainsThisHost := false}}
{{range $host := getvs "/my/keys/hosts/*"}}
  {{if eq $host (getenv "HOSTNAME")}}
    {{$arrayContainsThisHost = true}}  <== requires Go 1.11
  {{end}}
{{end}}

{{if eq $arrayContainsThisHost false}}
...

Sprig also makes sense here because it's included in Helm (for Kubernetes).
