Move loadavg and swapactivity to sshlogin-dir, too.

Computing the number of cores and max-logins on remote systems is slow, and fails if one of the sshs get stuck.

So cache this information in ~/.parallel/tmp/sshlogin/*

Move the linelength to there aswell.

cat sshlogins | parallel --plain --results ~/.parallel/tmp/sshlogin/{1}/{2} 'echo | ssh {1} parallel --{2}' :::: - ::: number-of-cores number-of-cpus max-line-length-allowed
