Convert command success events to INFORMATION type

• I reviewed the Contributing Guide.
• I performed a cursory search to see if the bug report is relevant, not redundant, nor in conflict with other tickets.

Describe the bug
Similar to DS issue 107
FM is out-of-family with most of cFS in declaring successful command EIDs as DEBUG type, and also not in line with the cFE Developer's Guide s7.2. See additional reasoning here which makes a lot of sense.

Code snips

	#define FM_DELETE_CMD_EID 28

etc...
(~20 cases total)

Expected behavior
Successful/nominal command events should be defined as INFO type.
