create-cluster clean now will clean appendonlydir

[enjoy-binbin]

In #9788, now we stores all persistent append-only files in
a dedicated directory. The name of the directory is determined
by the appenddirname configuration parameter in redis.conf

Update create-cluster clean to clean this default directory.
Each node have a separate folder appendonlydir-{PORT}.
This PR also do some cleanups, logs and stricter wildcard matching.
Fixes #10222

@chenyang8094 FYI use case of multiple nodes in one folder.

maybe instead we wanna let each node have a separate folder?
current code gives each one a different appendfilename.
not sure if some users of this script expect it to sometimes start from old persistence files (on upgrade)?

yes, i also found this after submitting. i also do some cleanups(see if this needed)

@madolson @yossigo do you know if some users of this script expect it to sometimes start from old persistence files (on upgrade)?
if they are, we need to avoid changing the appenddirname..

@oranagra Maybe it's a kind of wishful thinking, but I tend to assume this script is only used for toy / test environments.

@oranagra Got, thank you.

[madolson]

AFAIK it's only used for test environments as well.
