[strongSwan] Pause between ipsec stop and ipsec start

I used to run into this when I was setting up my first strongswan 
connection (to a Cisco router). I believe the issue was occurring 
because I had my side set up with 'auto=start' or 'auto=route'. It would 
conflict with the other side's establishment phase when I was forcing 
the routing before the ESP tunnel could be established. Using just 
'auto=add' would let sessions negotiate fully, then bring up the routes.

I could be wrong, I'm by no means an expert on all this. I'm also 
running on the 5.x branch, rather than 4 like you.
