  - Refactoring multiple plugins

    Refactoring below plugins in sdnr/wt/common/pom.xml :

    1) org.codehaus.mojo : exec-maven-plugin -> changing executable to bash so that it can run on windows too
    2) com.github.alexcojocaru : elasticsearch-maven-plugin -> skip if tests are skipped during maven build

    Adding create dir step in es-intit.sh :
    sdnr/wt/data-provider/database/src/main/resources/es-init.sh -> cmd_initfile() -> mkdir -p $( dirname $INITFILENAME )
