Since the dynamic allocations in raxIterator are only used for deep walks, memory
leak due to missing call to raxStop can only happen for rax with key names longer
than 32 bytes.
Out of all the missing calls, the only ones that may lead to a leak are the rax
for consumer groups and consumers, and these were only in AOFRW and rdbSave, which
normally only happen in fork or at shutdown.

Specifically, the key passed to the module aof_rewrite callback is a stack allocated robj. When passing it to RedisModule_EmitAOF (with appropriate "s" fmt string) redis used to panic when trying to inc the ref count of the stack allocated robj. Now support such robjs by coying them to a new heap robj. This doesn't affect performance because using the alternative "c" or "b" format strings also copies the input to a new heap robj.

in case the rdb child failed, crashed or terminated unexpectedly redis
would have marked the replica clients with repl_put_online_on_ack and
then kill them only after a minute when no ack was received.
it would not stream anything to these connections, so the only effect of
this bug is a delay of 1 minute in the replicas attempt to re-connect.

Before this commit, the output of "./runtest-cluster --help" is incorrect.
After this commit, the format of the following 3 output is consistent:
./runtest --help
./runtest-cluster --help
./runtest-sentinel --help

interestingly the latency monitor test fails because valgrind is slow
enough so that the time inside PEXPIREAT command from the moment of
the first mstime() call to get the basetime until checkAlreadyExpired
calls mstime() again is more than 1ms, and that test was too sensitive.
using this opportunity to speed up the test (unrelated to the failure)
the fix is just the longer time passed to PEXPIRE.

in the majority of the cases (on this rarely used feature) we want to
stop and be able to connect to the shard with redis-cli.
since these are two different processes interracting with the tty we
need to stop both, and we'll have to hit enter twice, but it's not that
bad considering it is rarely used.

* update daily CI to include cluster and sentinel tests
* update daily CI to run when creating a new release
* update release scripts to work on the new redis.io hosts
(cherry picked from commit 7f19a04f0f049720ff5f84f3ab1aa81014f2f4ed)
* fix description about ZIP_BIG_PREVLEN(the code is ok), it's similar to
antirez#4705
* fix description about ziplist entry encoding field (the code is ok),
the max length should be 2^32 - 1 when encoding is 5 bytes
