Hello,

I try to use your exporter with a Redis cluster that had a password with special characters.

Take as example : password = suds*$d@?2\

because of these characters, I was not able to connect the IoRedis. Even in using url encode.

So I develop a PR to allow passing Redis Password as an options

[autarchprinceps]

This can be added to the URL infront of the host, instead of requiring a separate env variable.

[AnthonyDurussel]

But if you have any special characters in the password, you cannot add it to the URL. Even if you use url encode.

[maxaggedon]

Other than special characters, having a separate environnement variable for password allows to retrieve it from a secret if you use this image in kubernetes

hi @maxaggedon I fixed the log the password. Can you merge this PR in the next release ?

@AnthonyDurussel I reported a potential security issue because I saw it, but I don't have write access on this repo, sorry.
