support path parameterization for file data

[Codelone]

Sometimes， we need to use a variable path to execute commands, so replace the file path of PARQUET、ORC、 JSON、CSV by adding arguments。
if need use ，need to set " -f -p param1=/home/xxx.csv,param2=/home/xxx.csv "
then tag/edge path in application.conf needs to be set to param1, param2.
if don't need it , don't use " -f -p ".

Great improvement~~
Maybe we need some docs/examples as well :)

In practical using, we will create a scheduler task, the csv file path is fixed, but our file name maybe changing, such as a date suffix, so we need to use a variable path.

it's a great work, thanks!
maybe we should use more understandable variable name，how about change file to variable， path to param?

[Nicole00]

this pr look good to me, and the code needs to be formatted please. @Codelone

[Codelone]

It has been changed，please check it。

[Nicole00]

I just noticed there's no test for the variable path for config file, could you please add some test to make sure it works?

test case method configsWithVariableSuite
