[BUG]: enhanced multipath.conf file for PowerStore FC and iSCSI

[dancohen21]

Bug Description

as a follow up to CSM issue 1595

the section in the CSM documentation where it talks about configuring the multipath.conf file
under: https://dell.github.io/csm-docs/docs/deployment/csmoperator/drivers/powerstore/#linux-multipathing-requirements

defaults {
user_friendly_names yes
find_multipaths yes
}
blacklist {
}

and where it wraps it in a machineconfig to apply...

apiVersion: machineconfiguration.openshift.io/v1
kind: MachineConfig
metadata:
name: workers-multipath-conf-default
labels:
machineconfiguration.openshift.io/role: worker
spec:
config:
ignition:
version: 3.2.0
storage:
files:

• contents:
  source: data:text/plain;charset=utf-8;base64,ZGVmYXVsdHMgewp1c2VyX2ZyaWVuZGx5X25hbWVzIHllcwpmaW5kX211bHRpcGF0aHMgeWVzCn0KCmJsYWNrbGlzdCB7Cn0K
  verification: {}
  filesystem: root
  mode: 400
  path: /etc/multipath.conf

This is not the best configuration. a more appropriate multipath.conf file is specified in the Host connectivity guide on page 202. This is what should be documented and encoded for the machineconfig for powerstore. It seems best to have tighter alignment between the PowerStore Linux best practices documented in the host connectivity guide and the CSM documenation if it is deemed applicable.
