Bug Description

MongoDB cluster is not created during deploy.

The parameter /proc/sys/net/ipv4/tcp_keepalive_time is too small for deploy mongodb. MongoDB guide recommends to use the following value:
echo 300 > /proc/sys/net/ipv4/tcp_keepalive_time

If a mongo role was shared with a controller role, the suggested fix would interfere with existing failover scenarios which rely on a 30 seconds value for TCP KA. So, this fix requires additional verification against any potential regressions.

    Set tcp_keepalive_time to 300 on MongoDB nodes

    The default value of 30 seconds may cause socket errors between members
    of a cluster. Setting it to 300 is recommended in the official
    documentation[1].

    Exclude controllers not to overwrite the fix for
    Ic9d491f4904a5e665278027fc37254003c4b5172.
