Clean up comments in config member ZWESIP00

[OnnoVdT]

The comments in samplib/zis/ZWESIP00 are incomplete and do not line up with what is in the online documentation, so somebody who knows what the configuration options are should review this file and clean it up, together with the matching online documentation. Once all the data is in, I can help with tweaking the look and feel to make it fit in with the rest of Zowe sample members.

• document how to write a comment, you currently use 2 different methods
• all uppercase is not pleasant to read
• document that keywords are strung together with a period
• document valid and default values for keywords
• not all PLUGIN keywords are documented
• online docs say ZSS uses SAF class FACILITY, here you insinuate that a new class, ZOWE, is used (not a fan of this, as now we must also provide sample commands to create a class in RACF/ACF2/TSS).

looking at the online docs again, I now see that they use the wrong term. It's the FACILITY class but the ZOWE profile, not class.
