Named parameters (Option) unavailable when using raw_arguments=true

[dominiquevocat]

Describe the bug

when a command uses support_rawargs named parameters are not passed. Used to work with splunklib 1.6.12, doesn't seem to work with splunklib 1.7.0

To reproduce

commands.conf:
[xx]
passauth = true
chunked=true
supports_rawargs = true
local = true

code snippet:
@configuration(local=True)
class xx(GeneratingCommand):
splunk_server = Option(require=False, default="*" )

results in always being the value "*" and changing it to require=True causes it to fail with "A value for "splunk_server" is required" but it is in the splunk search.

Expected behaviour

Named parameters are available when using raw_arguments = true and the above mentioned settings in commands.conf - i can reproduce it as working with splunklib 1.6.12

splunklib 1.6.16 also causes the same issue
