Our CI slaves have no enough RAM

[Daniil Trishkin]

While running install tests of ceilometer rpm package we get "Cannot allocate memory" error. So we need more memory on slaves for testing purposes.

please add more information about this problem (jenkins job url, list of packages, etc)

1. Error message is not informative

+ echo '<failure type="Failure" message="failed">'
+ echo '<![CDATA['
+ tail -n 20 testing-openstack-ceilometer-common
+ echo ']]>'
+ echo '</failure>'

Further investigation led to "Cannot allocate memory" error.

Error is triggered by
https://review.fuel-infra.org/#/c/12209/81/tests/runtests.sh

As you could see there are a lot of running services inside this tests and this is a root cause.
I can't say for sure which number of bytes we need exactly.

2. Another problem is just incorrect runtests.sh - services should be killed after each step of test.

It could be great if we could have more informative logs and ideally output of runtests.sh.

Artem, please take a look to log file with errors from this jenkins job http://osci-jenkins.srt.mirantis.net:8080/job/master.mos.install-rpm/1661/artifact/report.xml

Increase RAM for test VM to 3GB

Running functional tests from runtests.sh script
in some cases requires more that 1GB of RAM,
so let's increase it
