add a script to do metad folder scp

[liuyu85cn]

In our forum, some user complain lack of mete transfer tools.

this tool is a simple wrapper to scp to copy local folder of metad to another (remote)place
it afford 4 options:
1. -f (from) local metad dir
2. -t (to) remote destination
3. -u (update) any configs need to be changed
different configs should be seperated by ':'
each config has to be the form of "local_ip=172.0.0.1"

for example

 ./meta-transfer-tools.sh -f /path-to-src/metad1 -t bob@172.0.0.1:/path-to-dst -u local_ip=172.0.0.1:port=10086

this is not a well discussed solution for this, and I'm not very good at shell, any suggestion is welcome.

Don't forget to install this script

Some suggestions:

1. It seems src is the dir where we install nebula, so how about try to read the conf under src (not only change the conf after scp is done). One of the most improvement is that, we can get the data_path of meta from the conf.
2. Better only change conf after scp is done
3. meta_server_addrs could be consider to modified as well. (If the script is designed to only from 1 to 1, not m to n, some documents need to be add later, could contact @whitewum later)
