Resource adapter subsystem configuration descriptions: wm-security

These descriptions of wm-security may want to be reviewed.

• There is a typo in the resource description of wm-security:

  Toggle on/off wm.security for this resource-adapter. In case of false all wm-security-* parameters are ignored, even thei defaults.

• For wm-security-mapping-required, the description seems to refer to documentation sections:

  Defines if a mapping is required for security credentials. A value of false means Case 1 as defined in section 16.4.3, and a value of true means Case 2 as defined in section 16.4.4.

  However these sections can me moved or removed, and the numbers will often change. I'm not even sure what content this refers to. We shouldn't hard-code documentation references.

• Ending the description with a full stop is also missing on many descriptions.
