Khai Do 38dc89814f Increase the HTTP incoming connection queue
Upstream Gerrit confirms that the default value for the httpd.maxQueued
value was set too low.  The fix[1] for it was to change the default to
200 however the fix is only in version 2.12+ not in 2.11.

clarkb confirmed that we are seeing the same error (stack trace linked
in 1st ml thread in upstream fix[1]) in review.o.o logs.  This likey
indicates that VM starvation (due to GC) is making Gerrit to slow to
process incoming client requests so it pushes more requests into the
queue than it can handle.  Once the queue is exhausted the requests
get rejected with 500 errors.  Increasing the max number of client
connections may help alleviate this situation until Gerrit can catch
up.

# This limit must be several units higher than the total number of
# httpd and sshd threads as some request processing code paths may need
# multiple connections.
# database.poolLimit = 1 + max(sshd.threads,sshd.batchThreads)
# + sshd.streamThreads + sshd.commandStartThreads

# https://gerrit-review.googlesource.com/#/c/70627
# httpd.maxWait:
# 12:07 <@spearce> httpd.maxwait defaults to 5 minutes and is how long gerrit
# waits for an idle sshd.thread before aboring the http request
# 12:08 <@spearce> ironically
# 12:08 <@spearce> ProjectQosFilter passes this value as minutes
# 12:08 <@spearce> to a method that accepts milliseconds
# 12:09 <@spearce> so. you get 5 milliseconds before aborting
# thus, set it to 5000minutes until the bug is fixed.
