The deleted paragraph seems like a carry over from a previous version of the document as Redis is no longer mentioned as part of the base image template.
* Move setting of default EnvVarFormat to the Prepare function
* Add generated hcl2 structure for the updated Shell provisioner config
* Move `EnvVarFormat` field to shared common shell type
* Add description for the `env_var_format` parameter
* Update `env_var_format` when used with `use_env_var_file`
It is simply the best/simplest solution and trying to prevent users from passing and integer here would be like opening a can of worms. Because:
* we cannot make mapstructure validate our duration string ( with an UnmarshalJSON func etc.)
* we cannot make mapstructure spit a string instead of a duration and packer will decode-encode-decode config.
* the hcl2 generated code asks for a string, so this will be enforced by default.
Before this commit it was possible to set a duration using an integer or a float. Go's time.Duration is an int64 internally an mapstructure will take advantage of this and load the number as a int64 but `1` means one ns which is unexpected/confusing. To avoid confusion and enforce readability this forces users to pass a string with a unit for a duration; ex "56s".
