This patch backports a fix which will show the correct usage screen for
command line flags.
This is considered a temporary fix until the code has been refactored.
Newer versions of the cli library require that the flag set is populated
when Help() is called or that it is populated within Help() itself.

DebugConfig and will be documented to change.
Fixes#3530
* config: fix tests
* doc: update api documentation for /v1/agent/self
This patch updates the go-discover library to use the new config parser
which uses a different encoding scheme for the go-discover config DSL.
Values are no longer URL encoded but taken literally unless they contain
spaces, backslashes or double quotes. To support keys or values with
these special characters the string needs to be double quoted and usual
escaping rules apply.
Fixes#3417
