Undocumented fabric-ca-client flag: -d

[joaormatos]

The fabric-ca-client command supports an undocumented -d flag that sets the logging level to debug, overriding the --loglevel option.

This flag is used in tests and examples, but I couldn't find documentation for it.

It's defined (and marked as hidden) here:

fabric-ca/lib/clientconfig.go

Line 44 in d3c7ae2

Debug bool `opt:"d" help:"Enable debug level logging" hide:"true"`

This tripped me up because I was following example invocations of the command (which include the -d flag) and I was trying to reduce their verbosity via --loglevel but it didn't seem to work.
Only when I noticed and removed the mysterious flag did it start working as expected.
