escape apostrophe in attribute

[badsector3]

Hi.

I try to pass multiline to lwrp-prospector.yml which looks like this:
           multiline_pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}'
Instead I am getting in lwrp-prospector.yml: 
       multiline_pattern: "^[0-9]{4}-[0-9]{2}-[0-9]{2}"

How can I get multiline_pattern: '^[0-9]{4}-[0-9]{2}-[0-9]{2}' to be written into prospector.yml?
I tried on filebeat 0.4.9 and 1.4.0 - the same output.

Hi. Any updates on this?

@badsector3 I will take a look.

Looks like that is the default behavior of to_yaml. Perhaps there is a way to define string type to use single quote.
