Fixes multiple issues with retry function in rhel-registration.

There were multiple issues in retry() in rhel-registration:
 - There was no need for it to be recursive (local variables
   got overwritten)
 - There was no delay between multiple attempts, leading to faster but
   more frequent failures.
 - The max number of attempts was set too low for some environements.

With this patch, rhel-registration now works more reliably with slow-links
for portal registration and does not attempt to DDos the portal or your
satellite server.
