tcpkeepalive: support setting TCP keep-alive parameters on Solaris <11.4 
Solaris didn't support TCP_KEEPIDLE and TCP_KEEPINTVL until 11.4,
before that it use TCP_KEEPALIVE_THRESHOLD and TCP_KEEPALIVE_ABORT_THRESHOLD
as the substitute. Therefore, for Solaris <11.4 we need to use this substitute
for setting TCP keep-alive parameters.

Closes #13864

--keepalive-time

Set the time a connection needs to remain idle before sending keepalive probes and the time between individual keepalive probes. It is currently effective on operating systems offering the TCP_KEEPIDLE and TCP_KEEPINTVL socket options (meaning Linux, *BSD/macOS, Windows, Solaris, and recent AIX, HP-UX and more). Keepalive is used by the TCP stack to detect broken networks on idle connections. The number of missed keepalive probes before declaring the connection down is OS dependent and is commonly 8 (*BSD/macOS/AIX), 9 (Linux/AIX) or 5/10 (Windows). This option has no effect if --no-keepalive is used.

If unspecified, the option defaults to 60 seconds.
