Description of problem:
Get the error below when runing the CR by using the `helm-operator`:

[root@preserve-olm-env data]# oc logs example-nginx-7df4447d79-jx8dd

example-nginx-7df4447d79-jx8dd          0/1     CrashLoopBackOff   3          70s


Version-Release number of selected component (if applicable):
4.6
Downstream helm-operator

How reproducible:
always

Steps to Reproduce:
1. Init a Helm type nginx-operator by using the `operator-sdk`.
[root@preserve-olm-env nginx-operator]# pwd
/data/goproject/src/github.com/example-inc/nginx-operator
[root@preserve-olm-env nginx-operator]# ls
build  deploy  helm-charts   watches.yaml

2. Compile the downstream helm-operator binary.
[root@preserve-olm-env openshift]# git clone git:openshift/ocp-release-operator-sdk.git
...
[root@preserve-olm-env ocp-release-operator-sdk]# make build/helm-operator
[root@preserve-olm-env ocp-release-operator-sdk]# ls -l ./build/helm-operator 
-rwxr-xr-x. 1 root root 55631400 Sep  2 02:38 ./build/helm-operator

3. Login a OCP 4.6 cluster.
[root@preserve-olm-env nginx-operator]# oc project
Using project "openshift-marketplace" on server "https://api.jiazha0901.qe.devcluster.openshift.com:6443".

4, Deploy the CRD.
[root@preserve-olm-env nginx-operator]# oc create -f deploy/crds/example.com_nginxes_crd.yaml
...
[root@preserve-olm-env nginx-operator]# oc get nginx -A
No resources found

5, Set the "OPERATOR_NAME" value and run this nginx-operator by using the helm-operator.
[root@preserve-olm-env nginx-operator]# export OPERATOR_NAME=nginx-operator
[root@preserve-olm-env nginx-operator]# ./helm-operator run
{"level":"info","ts":1599029881.6350155,"logger":"cmd","msg":"Go Version: go1.14"}
{"level":"info","ts":1599029881.6350768,"logger":"cmd","msg":"Go OS/Arch: linux/amd64"}
{"level":"info","ts":1599029881.635086,"logger":"cmd","msg":"Version of operator-sdk: v0.19.0"}
...

6, Deploy a nginx CR.
[root@preserve-olm-env nginx-operator]# oc create -f deploy/crds/example.com_v1alpha1_nginx_cr.yaml
...

Actual results:
The CR created sucecssfully, but its pod is crashing.

[root@preserve-olm-env data]# oc get pods
NAME                                    READY   STATUS             RESTARTS   AGE
...
example-nginx-7df4447d79-jx8dd          0/1     CrashLoopBackOff   3          70s
...

[root@preserve-olm-env data]# oc logs example-nginx-7df4447d79-jx8dd
2020/09/02 07:05:12 [warn] 1#1: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:2
nginx: [warn] the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:2
2020/09/02 07:05:12 [emerg] 1#1: mkdir() "/var/cache/nginx/client_temp" failed (13: Permission denied)
nginx: [emerg] mkdir() "/var/cache/nginx/client_temp" failed (13: Permission denied)


Expected results:
The CR pod should works well.
