[BUG] Add --nodigest and --nosignature flags to rpm call in yumpkg module

[bdrx312]

Is your feature request related to a problem? Please describe.

yumpkg list_pkgs makes a subprocess command call to rpm -qa to list the packages (

salt/salt/modules/yumpkg.py

Lines 747 to 752 in caa5e39

	cmd = [
	"rpm",
	"-qa",
	"--queryformat",
	salt.utils.pkg.rpm.QUERYFORMAT.replace("%{REPOID}", "(none)") + "\n",
	]

). rpm -qa does digest and signature checking by default. list_pkgs is does not need to verify checksums and signatures and therefore can reduce the time to list the packages by disabling the digest and signature checking with the --nodigest and --nosignature flags.

Describe the solution you'd like
Add the --nodigest and --nosignature to the cmd variable that is passed to cmd.run in the list_pkgs function of salt/modules/yumpkg.py

Additional context

Here are a couple of example timings of rpm -qa before and adding the flags on my rhel 8 ec2 instance:

$ free && sync && echo 3 > /proc/sys/vm/drop_caches && free
$ time rpm -qa > /dev/null

real: 0m2.944s
user: 0m1.689s
sys:  0m0.163s
$ time rpm -qa > /dev/null

real: 0m1.740s
user: 0m1.644s
sys:  0m0.079s
$ free && sync && echo 3 > /proc/sys/vm/drop_caches && free
$ time rpm -qa --nodigest --nosignature > /dev/null

real: 0m1.319s
user: 0m0.259s
sys:  0m0.147s
$ time rpm -qa --nodigest --nosignature > /dev/null

real: 0m0.366s
user: 0m0.235s
sys:  0m0.099s

@bdrx312 I know you were working on a PR were you able to get that started?

No I have been busy and haven't had time to figure out how to setup a saltstack development environment on Windows with vagrant yet. I created a fork and committed the change. If someone wants take the changes and pick up from there they can see it here https://github.com/bdrx312/salt. I am not sure when I will have time.

moving this to bug as the speed up is enough that this could be considered a bug in speed.
