Basic functionality of collecting system info

This is the 1st working release of TiDB-Insight, which now supports collecting:

• Partition information & stats
• Progress info of TiPD/TiDB/TiKV server (multiple instance on one host is not supported yet)
• Runtime trace data using perf (disabled by default)
• Application logs of TiPD/TiDB/TiKV server and system log (disabled by default)
• Dump critical system configurations (disabled by default)
• Runtime information of cluster from PD's API (enabled by default, optionally using --pd-host and --pd-port if there's no pd-server running on localhost)

Collected data are saved to data under the project root.

To build the collector binary, install Go and run make.
