Using secrets when generating config

[cosandr]

Is your feature request related to a problem? Please describe.

Perhaps this is intentional, the bitwarden function is not available when chezmoi init tries to generate a config file from a template.

$ chezmoi init -v --debug
Reinitialized existing Git repository in /home/andrei/.local/share/chezmoi/.git/
2020/02/10 17:31:58 Run("/usr/bin/git init") (1.59716ms)
( cd /home/andrei/.local/share/chezmoi && /usr/bin/git init )
chezmoi: template: chezmoi.toml:2: function "bitwarden" not defined

Describe the solution you'd like

For chezmoi init to have the secret functions available like the other templates do.

Describe alternatives you've considered

Rename .chezmoi.toml.tmpl to something else, for example make_chezmoi_cfg and run chezmoi cat instead.

mkdir -p ~/.config/chezmoi
chezmoi cat ~/make_chezmoi_cfg > ~/.config/chezmoi/chezmoi.toml

Additional context

$ cat make_chezmoi_cfg.tmpl
[data]
{{- range (bitwarden "item" "chezmoi").fields -}}
    {{- if eq .type 1.0 }}
    {{ .name }} = "{{ .value }}"
    {{- end }}
{{- end -}}

$ chezmoi cat ~/make_chezmoi_cfg
[data]
    public_email = "<VALUE>"
    public_name = "<VALUE>"
    private_email = "<VALUE>"
    private_name = "<VALUE>"
    ssh_domain = "<VALUE>"
    ssh_port = "<VALUE>"

Thank you very much for the detailed feature request :)

590 should fix this, and goes further to make all template functions available when generating the config.
