issue2550949: Rate limit password guesses/login attempts.
Generic rate limit mechanism added. Deployed for web page
logins. Default is 3 login attempts/minute for a user. After which one
login attempt every 20 seconds can be done.
Uses gcra algorithm so all I need to store is a username and timestamp
in the one time key database. This does mean I don't have a list of
all failed login attempts as part of the rate limiter.
Set up config setting as well so admin can tune the rate. Maybe 1
every 10 seconds is ok at a site with poor typists who need 6 attempts
to get the password right 8-).
The gcra method can also be used to limit the rest and xmlrpc
interfaces if needed. The mechanism I added also supplies a status
method that calculates the expected values for http headers returned
as part of rate limiting.
Also tests added to test all code paths I hope.
