Add environment variable for embedded ES container (#410)

* Add same environment variables for the embedded elastic search container as in docker-compose.
* Limit the memory (Xms/Xmx) to 128m because since ES 7.11.0, heap settings are based on node roles and total system memory #65905. Heap memory default values are computed as :
50% of total system memory when greater than 1 gigabyte up to a maximum of 31 gigabytes
cf. gridsuite/deployment@42d4372.
We cannot accept to allocate 16Go for an embedded ES.
