Missing documentation for ldap.cache-ttl property in presto-password-authenticators

[armaseg]

Hi All,

I noticed that the ldap.cache-ttl property in presto-password-authenticators is not documented. It can be a really painful if you are playing with different users/passwords on LDAP and you don't know that there is a cache.

Thanks!
