Description

The main idea is to increase or decrease some sysctl params which usually need to change by default. e.g.
nf_conntrack_tcp_timeout_established by default 432000/60/60/24 = 5 days

net.netfilter.nf_conntrack_max
net.ipv4.tcp_mem
net.ipv4.udp_mem
net.ipv4.tcp_rmem
net.ipv4.udp_rmem_min
net.ipv4.tcp_keepalive_time
net.ipv4.tcp_keepalive_probes
net.ipv4.tcp_keepalive_intvl
net.core.somaxconn
net.core.netdev_max_backlog
net.ipv4.tcp_max_syn_backlog
net.ipv4.tcp_syn_retries
net.ipv4.tcp_synack_retries
net.core.netdev_max_backlog
net.ipv4.neigh.default.gc_thresh1
net.ipv4.neigh.default.gc_thresh2
net.ipv4.neigh.default.gc_thresh3
net.ipv6.neigh.default.gc_thresh1
net.ipv6.neigh.default.gc_thresh2
net.ipv6.neigh.default.gc_thresh3
net.ipv4.tcp_congestion_control
net.ipv4.tcp_slow_start_after_idle
net.ipv4.tcp_max_tw_buckets

The main idea to add some automation logic for calculation:

vyos@vyos# set system sysctl profile 
Possible completions:
   <text>       Sysctl profile
   Profile1     
   Profile2     
   auto

I suppose we need a clearer idea of what we do with sysctl values.
