Description of problem:

According to https://github.com/openshift/cluster-etcd-operator/blob/release-4.9/pkg/operator/defragcontroller/defragcontroller.go#L158 `DefragDialTimeout` will be used as timeout when running `etcd` defrag. When checking, this appears to be set to 45 seconds (see https://github.com/openshift/cluster-etcd-operator/blob/release-4.9/pkg/etcdcli/etcdcli.go#L41).

When running `etcd` defrag activity on large OpenShift Container Platform 4 - Cluster this does not appear to be enough as it occasionally will fail because it defrag does not complete within the expected 45 seconds.

Failed to defragment etcd member[https://localhost:2379] (context deadline exceeded)

Version-Release number of selected component (if applicable):

 - OpenShift Container Platform 4.9.23

How reproducible:

 - Random but expected to fail more often when `etcd` is beyond 5 GB in space

Steps to Reproduce:
1. Setup OpenShift Container Platform on AWS with Master and Worker of type m5.4xlarge
2. Install Elasticsearch, Logging, Jaeger, NFD, GitOps, Pipelines, Kiali and Service Mesh Operator
3. Run `for i in {5000..7125}; do oc new-project project-$i; oc create configmap project-$i --from-file=/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt; done`
   Mind `/etc/pki/ca-trust/extracted/openssl/ca-bundle.trust.crt` is about 264K in size and therefore something in that area should be used

Actual results:

Once in a while `etcd` defrag will timeout with this size as timeout is set to 45 seconds. Considering that Clusters may have +5 GB in `etcd` size it's expected that defrag will fail most of the time and therefore never happen. Hence increasing the timeout is required or another approach needs to be found.

Expected results:

If `etcd` defrag is suppose to happen is should be able to complete no matter of the size of the `etcd` database.
