Proposal: Add the ability to use os variables in jiralert.yml

[Ikalinichev]

Hi
As I can see there is a lack of ability to use os env variables in jiralert.yml. I wrote a helm chart for Jiralert and I am deploying it via terraform for the different AWS accounts. It is impossible for me to store credentials to Jira in plaintext config.
Proposal:
To add the ability to use os env variables just add content = []byte(os.ExpandEnv(string(content))) in func LoadFile of config.go file.
It works fine for me.

defaults:
  api_url: ${JIRA_URL}
  user: ${JIRA_USER}
  password: ${JIRA_PASSWORD}

It would be great if you include it in the next release.
Thanks.

Fixed by #125

This should be closed, due to splitt3r's merged PR, right?

Hi, do you have an example how to define the variables in jiralert.yml to be take by env_var_substitution as implemented in #125 ?

I have defined in jiralert.yml

defaults:
    user: ${JIRA_USER}

but it does not work, is the syntax correct ?
Nevermind, I have found the syntax

defaults:
  user: $(JIRA_USER)
