Problem with the new format of /usr/sap/services records and pre-freeze and post-thaw HANA scripts

[akx-github]

Is your feature request related to a problem? Please describe.

SAP have implemented integration of the HANA Instance records into systemd / systemctl and activates this feature with all newer implementations of HANA starting with SLES15 and HANA 2 SPS7 and changed the records of HANA Instances

from the known 'classic format':
LD_LIBRARY_PATH=/usr/sap//...; export LD_LIBRARY_PATH; /usr/sap//.../sapstartsrv pf=/usr/sap//... -D -u adm
to 'systemd format':
systemctl --no-ask-password start SAP_ # sapstartsrv pf=/usr/sap//...

The hana-pre-freeze.sh und hana-post-thaw.sh can not understand the nwe foramt and unable to detect HANA instances.

Describe the solution you'd like
The scripts should understand both formats the newer and the old ones.
