Stefan Haberland 5737a57920 zdsfs: coordinated read access ...

For data consistency it is essential that datasets are not modified by
z/OS applications during zdsfs access. This is currently ensured by
manually setting the device offline in z/OS before mounting it in Linux.

This patch improves the usability and data security by making this manual
step obsolete.
Before opening a dataset zdsfs will obtain an ENQ to mark it as in use for
z/OS and release the ENQ when closing the dataset.
A timer is set up that pings the z/OSMF REST services with the ENQ to
prevent it from a timeout after 10 minutes.
The behavior of zdsfs can be configured in a new config file or with new
command line options.
