Get a new lb pid if existing pid is not alive
It's possible for the connection process associated with a pid in the
ibrowse_lb ets table to die, yet remain in the table, in which case
subsequent requests to the corresponding {Host, Port} will result in an
error like the following:
(node1@127.0.0.1)9> ibrowse:send_req("http://localhost:15984", [], get).
** exception exit: {noproc,
{gen_server,call,
[<0.2451.0>,
{spawn_connection,
{url,"http://localhost:15984","localhost",15984,
undefined,undefined,"/",http,hostname},
10,10,
{[],false},
[]}]}}
in function gen_server:call/2 (gen_server.erl, line 215)
in call from ibrowse:try_routing_request/14 (src/ibrowse.erl, line 377)
This checks whether the pid about to be returned from the table is alive,
and if not, the entry is deleted, and a new pid is obtained.
