OSP 17.1 deployment failing because of missing osp_rhel_mapping

[sanjaychari]

There is currently no osp_rhel_mapping for OSP 17.1.

jetpack/setup_undercloud.yml

Lines 5 to 13 in b48d6bb

	osp_rhel_mapping:
	10: 7.7
	13: 7.9
	14: 7.7
	15: 8.0
	16: 8.1
	16.1: 8.2
	16.2: 8.4
	17.0: 9.0

This causes the following error.

OSP 17.1 GA will use RHEL 9.2. We should set osp_rhel_mapping to 9.1 for now for OSP 17.1, and later change it to 9.2.
