Subject: [PATCH 1/2] fence_lpar: Fix list-status action

The `list-status` action prints "UNKNOWN" status for all LPARs when
`--hmc-version` is `"4"` or `"IVM"`.

This commit fixes that by mapping the statuses returned by the HMC
(e.g., "Running") to the statuses that the fencing library expects
(e.g., "on").

Resolves: RHBZ#1861926

Subject: [PATCH 2/2] fence_lpar: Reduce code duplication in get_lpar_list

The logic for HMC version 4 and HMC version IVM are the same except for
the use of a different separator character. This commit condenses them
into one block.
