Add framework of server parser 

a. The parser fetch and parse one command per loop. The prefix is
the command prefix without parameter. For example, the prefix of
"AT+CLIP=1" is "+CLIP".

b. Search registered notification node in command_list. Invoke the
callback if found.

c. Termiate the execution if the result is an error. Otherwise,
parse next command.
