st2clientConfig issue with jobs.extra_hooks

[cars]

We're trying to use extra_hooks in a k8s deployment and running into an issue where the additional jobs we define get run. But we find as we try to run additional st2 commands that we're seeing an error along the lines of:

configparser.DuplicateSectionError: While reading from '/root/.st2/config' [line 2]: section 'credentials' already exists

In looking into this issue I see that at

stackstorm-k8s/values.yaml

Lines 925 to 928 in 415e3a6

	st2clientConfig: |
	[credentials]
	username = ${ST2_AUTH_USERNAME}
	password = ${ST2_AUTH_PASSWORD}

creating a st2clientConfig value that [credentials] is included in the config value.
But in the jobs template '[credentials]' is being pre-prended to the st2clientConfig value:

stackstorm-k8s/templates/jobs.yaml

Lines 663 to 666 in 415e3a6

	cat <<EOT > /root/.st2/config
	[credentials]
	{{- tpl $.Values.jobs.st2clientConfig $ | nindent 12 }}
	EOT

resulting in a config file that looks like:

[credentials]
[credentials]
username=st2admin
password=fred

Good find!
