Password with Dollar Sign in config.yaml not possible

[KevDi]

I have noticed that i could not use the $ in an Password if i want to use the config.yaml file.
As i looked through the code i think the problem is Line 171 in the config.go file.
Inside the Function LoadMetricsConfiguration this call is made:
expanded := os.ExpandEnv(string(content)).
From what i saw it is definitly needed to expand possible environment variables used in the configuration.
But is there a way to escape the $ sign in for example passwords? I tried with $$ or \$ but none of those worked.
If it is generally not possible then maybe a hint in the Readme would be good so that others also know that $ Signs in Passwords could not be used when using the config.yaml

Thanks for reporting this, it looks like a limitating of os.ExpandEnv. I think we need to look at an alternative to this function, e.g., external library.
