Remove double quotes in spark/bin batch files to avoid cutting off ar…

…guments that double quoted as contain special character.

To simply validate (for example, mysql connection string), cannot just start it :
spark-submit.cmd --jars just-to-start "jdbc:mysql://localhost:3306/lzdb?user=guest&password=abc123" my_table

After this fix :
(1) Keep not working : full path has space like "D:\opengit\spark\bin - Copy\spark-submit.cmd" --jars any-jars "jdbc:mysql://localhost:3306/lzdb?user=guest&password=abc123" my_table
(2) Keep working : currently can works.
(3) Will work by this fix: argument has quotes if full path no space.
By the way, I didn't change the pyspark , R, beeline etc. scripts because they seems work fine for long.

What's more in addition, a tool to quickly change the files in spark/bin if you like : https://github.com/qualiu/lzmw
(1) Remove quotes : lzmw -i -t "(^cmd.*?/[VCE])\s+\"+(%~dp0\S+\.cmd)\"+" -o "$1 $2" --nf "pyspark|sparkR|beeline|example" -p . -R
(2) Add/Restore   : lzmw -it "\"*(%~dp0\S+\.cmd)\"*" -o "\"$1\"" -p . -R
(3) Or remove the head : lzmw -f "\.cmd$" -it "^cmd /V /E /C " -o "" -p %CD% -R
