start working on issue IOTDB-355
Hi,
I'm now working on issue IOTDB-355, to implement some start-up checks in the distributed version.

Hi Yuyuan,
If you record the values of some immutable parameters into some system
file,
please add some descriptions in docs/Documentation/UserGuide/8-System
Design (Developer)/2-Files.md

Hi,
The issue IOTDB-355 is fixed. The start-up checks are implemented in the distributed version.
The new functions includes:
1. If a node tries to form the initial cluster as a seed node, the number of seed-nodes in its cluster configuration will be checked to guarantee that it is no less than the quorum, which is an integer holding minimum the value, identical to or greater than half of the replication number.
2. If a node tries to join the cluster, the request will hold the current status of the new node, containing partition interval, hash salt and replication number. Besides the previous implemented constraints, the learder will check the status of the new node, which should be consistent with the cluster's configuration.
Best,
