templates: add wrap helper function

deepcube · ldelossa · commit 0e3082fab6e1 · 2020-09-30T11:51:06.000-04:00
Add "wrap" command to TemplateProcessor.  Use
github.com/mitchellh/go-wordwrap to wrap lines on word breaks at
a given length.  This can make long fields much more readable in
a terminal.  E.g.

	{{ .fields.description | wrap 76 | indent 2}}
