Simple filter to prefix all items from a list. Default prefix will be `--` but you can also pass a custom one.
## Example
```Yaml
my_list:
- item1
- item2
{{ my_list | prefix | join(' ') }}
# result:
# "--item1 --item2"
```
Or pass a custom prefix:
```Yaml
my_list:
- item1
- item2
{{ my_list | prefix(prefix='-') | join(' ') }}
# result:
# "-item1 -item2"
```
