Added manifest to enable/disable SCTP Autoload

SCTP module autoload is enabled/disabled by using
service-parameter sctp_autoload.

Full Parameter name:
"platform::params::sctp_autoload"

This change implements a runtime manifest which makes sctp module
changes.

By default: sctp_autoload is "enabled"

If sctp_autoload=disabled:
- SCTP Module doesn't get loaded by default post host
lock/unlock

If sctp_autoload=enabled:
- SCTP Moduel gets loaded by default post host
lock/unlock.

Test Plan:
PASSED: build-pkgs
PASSED: Deployed AIO-Standard
PASSED: Verify service parameter configuration using
        enabled/disabled values
PASSED: SCTP module loads/unloads after host-reboot
