Issue 13.7: copy-config

[Andy Bierman <abierman@cisco.com>]

Hi,

There are several problems with the copy-config command,
as it is currently defined:

13.7.2: too many options; no option discovery
         
  Most of the copy modes are optional:
    - <running> as target
    - <startup> as target
    - remote to remote copy

  There is no way to tell what the agent actually supports
  for source and destination parameters. 

13.7.3: limited usefulness without user named databases and files

  Apparently, the only mandatory behavior an application can
  count on is:
    if (#candidate)
       (1) copy <running> to <candidate>
    if (#candidate && #url)
       (2) copy remote-file to <candidate>
       (3) copy <candidate> to remote-file
    if (#candidate && #startup)
       (4) copy <startup> to <candidate>
    if (#url)
       (5) copy <running> to remote-file
    if (#startup && #url)
       (6) copy <startup> to remote-file

  Mode (1) and (2) are redundant because they are available
  via edit-config.  It's not clear why anyone would want
  to use mode (3). Mode (4) isn't that interesting since
  not many products have #candidate and #startup capability.
  Mode (5) and (6) are widely used by operators.

13.7.4: implicit format conversion not interoperable

  The format conversion "feature" of copy-config is not
  well defined and application developers don't have any
  way of knowing how XML <--> text translation will be
  done on the agent.  The mapping may be incomplete and
  there is no way to tell which text or XML bits do not have
  an appropriate mapping.

13.7.5: <url> mode not documented

  The text does not mention that <url> may be used in place
  of one of the config targets.  This just shows up in the 
  example.
  
13.7: Proposal

  Since this operation has several problems, and is not 
  very useful without user named configurations, it should 
  be removed and deferred until that feature is added in the 
  future.
