CI: Allow restart of the container if it fails on the first attempt

In CI we sometimes encouter fail of the gNB/UE deployment (and fail of
the pipeline) caused by unsuccsessful initialization of the USRP N310.
Restart the container if the health check fails during initialization.

Introduce a configurable parameter (from XML) to set max number of
attempts for the container deployment.

Store logs from failed deployment attempts.
