Deprecate vcpu_pin_set for stx-openstack in favor of new configs

[Taimoor]

Brief Description
-----------------
StarlingX 4.0 provides the opportunity to use Application-isolated cores but the stx-openstack application override does not use sane values to take advantage of these cores. Also, starting from Ussuri, OpenStack is deprecating vcpu_pin_set in favor of cpu_dedicated_set and cpu_shared_set. These overrides must be supported to be generated via StarlingX commands (system host-cpu-* <command>)

Severity
--------
<Minor: System/Feature is usable with minor issue>

Steps to Reproduce
------------------
N/A

Expected Behavior
------------------
Correct overrides for stx-openstack application are generated

Actual Behavior
----------------
N/A

    Fix cpu_shared/dedicated_set config location

    Change I61514389b616db754b0d2f35deb0101f90dbdd02 removed the deprecated
    property vcpu_pin_set in favor of the newer cpu_shared_set and
    cpu_dedicated_set, but those new configs are placed under the [compute]
    section of nova.conf instead of [DEFAULT]. This is causing VMs to be
    scheduled on platform reserved cores. This commit will fix it.

    Add k8s proxy-body-size to horizon overrides

    The current network.dashboard.ingress.annotations in horizon's
    values.yaml helm charts do not include the kubernetes property
    'proxy-body-size'. This makes the resulting nginx.conf file in ingress
    add the default rule 'max_body_size 1m' to the horizon servers,
    which limits all http requests' size inside horizon to 1MiB, making it
    impossible to upload images larger than that to glance using the
    horizon GUI, for example.

    This change adds said property to the horizon overrides, making
    horizon's servers in nginx.conf include a 'max_body_size' of 2500MiB,
    which makes uploading images up to that size possible again.
