sap_swpm: Add optional flag to prevent redoing ownership change

[rnozaki]

This is a suggestion for issue #663

[berndfinger]

@rnozaki Thanks for the PR. I am currently working on a different solution, which would be:

• Change the ownership to root:root and permissions of the directories only, and of all files with file names starting with SAPCAR, to 0755. Use a role parameter named sap_swpm_set_directory_sapcar_permissions to optionally skip this step.
• Change the ownership to root:root and permissions of all files only, except SAPCAR to 0644. Use a role parameter named sap_swpm_set_file_permissions to optionally skip this step. If we find out during the testing phase that the permissions of the files have never been wrong, we can skip this step by default and use this role parameter to optionally enable this step.

What do you think about this?

Looks like a viable approach.

We just need to make sure that any ownership change that must be done, be done at least once (initially).

@rnozaki Please have a look at #665 .

Yes, that looks good, Bernd. That will cover what I requested in issue #663 .

When do you think this will be released?
