Implementing memory limitations in dockerizer jobs

[germa89]

As the title

Recent discussion in here #2479, led me to think that limiting the amount of memory used by docker container can improve its stability.
Therefore I'm limiting the amount of memory (--memory) to 6.5GB of RAM, and the amount of swap (--memory-swap) to the RAM (6.5GB) plus 10GB of the 14GB of the SSD memory (16.5GB).
I am also disabling out-of-memory killing (--oom-kill-disable) so the container will use all the memory available without being killed. Probably it wont be needed if memory is limited.
