Fix Save repo-setup hash content task

`Save repo-setup hash content` task dumps the proper dlrn md5 hash
for component/intergration/check pipeline.

Currently this task depends on cifmw_repo_setup_component_promotion_tag
whose default value is defined in role defaults.

In this case, this task is working wrongly. Let's use
cifmw_repo_setup_component_name length as a param to dump the
proper hash.
