Dependencies

PESSL has a dependency on the ESSL kit component

When adding PESSL kit component and want ESSL installed, ensure that the ESSL kit component is already added to the osimage, or, use the -a | --adddeps option on addkitcomp to automatically assign the kit dependencies to the osimage.

To add the pessl-computenode kit component to osimage rhels7.2-ppc64le-install-compute:
```
addkitcomp -a -i rhels7.2-ppc64le-install-compute \
    pessl-computenode-5.2.0-0-rhels-7.2-ppc64le
```
