This commit updates the MLE attach process so that in the first attach cycle device tries a total of six MLE Parent Requests, the first two to routers only followed by four to routers and REEDs. For example, the six Parent Request message will be used before device can decide to act the leader. An MTD in the next attach attempt (if cannot find a parent in first attempt cycle), will go to the model of two Parent Requests (first to routers, then to routers/REEDs). This change impacts the time it takes for a device to start as leader (due to increased number of Parent Request and wait time). This commit updates different test scripts to address the change in the wait time. It adds a new `config.LEADER_STARTUP_DELAY` constants which is used for wait time for leader to start.
