[Bug] username and password parsing from URL does not handle percent encoding

[Geal]

the utils::parse_url_credentials method gets the username and password from the URL using its direct methods:

fred.rs/src/utils.rs

Lines 735 to 744 in aa7fc02

	pub fn parse_url_credentials(url: &Url) -> (Option<String>, Option<String>) {
	let username = if url.username().is_empty() {
	None
	} else {
	Some(url.username().to_owned())
	};
	let password = url.password().map(|s| s.to_owned());
	(username, password)
	}

But those methods return the value as a percent encoded string: https://docs.rs/url/latest/url/struct.Url.html#method.username

Return the username for this URL (typically the empty string) as a percent-encoded ASCII string.

So if we are parsing the config from the URL redis://default:abc%2F123@localhost:6379, then the password that will be sent to Redis would be abc%2F123 instead of abc/123
