Enable Keepalive to server role
This commit is for, enable the timeout setting with suggested
values for server(300sec) role. Server's keep_alive_pings is
true by default, so time to server role is become 300/2 sec.
It is used for to check server/client communication status
in every 150sec.
There is a timeout option to websocket stream, which is created
by boost library .By default, timeouts on websocket streams are
disabled. The way to turn them on is to set the suggested timeout
settings on the stream.
Idle Timeout is configured as 300sec to server role by default.
We can adjust the timeout value which we want exactly by changing
the idle_timeout.
Depends on keep_alive_pings , the suggested value of the idle
timeout will be consider. Keep_alive_pings of server role is
set to `true` by default in boost library. So idle_timeout of
server role is consider as 300/2 sec by default.

Tested:
Redirected Virtual media. connection has established successfully.
Media instance gets redirected to host machine. Disconnected the
client network. Keepalive idle timeout for server role will found
stream miss communication status in next 150sec cycle, and virtual
media websocket will be stop gracefully.
Existing behaviour:
900sec (15 minutes) will be taken for closing the websocket
connection due to network disconnection.
