it does not handle redis with user and password on probes

[sibelius]

Description of the issue

I'm passing redis as external url

externalRedis:
  cache: 'redis://default:123456@myredis:6379/2'
  queue: 'redis://default:123456@myredis:6379/3'

all the probes

Context information (for bug reports)

{{- if .Values.externalRedis.cache }}
wait-for-it $(echo {{ .Values.externalRedis.cache }} | sed 's,redis://,,') -t 1;

sed does not work for user and password on redis uri

Steps to reproduce the issue

add an externalRedis

Observed result

it results in crashlookbackoff

Expected result

it should work

Stacktrace / full error message if available

[revant]

we need to have the command as bash script. sed needs improvement. that adds complexity and brittleness.

before we had tried nodejs / python. each time command runs it loads node or python causing unnecessary overhead for health check commands. There is any other way?
