[Clas12_software] Clara update

[golovach at jlab.org]

Dear Vardan and All,

I was not able to use the latest CLARA version for reconstruction.
I was able to reconstruct using one of the previous version.

Vardan, or someone else,
Could you please provide mode detailed instructions,
how can I run the whole chain simulation+reconstruction?

- the version of gemc
- do I need to make .hipo file from .evio, before running
the reconstruction?
- do I need to run bin/gemc-evio?
- which services in services.yaml were tested?

Regards,
  Evegeny
