docs: use newer ysql_hba_conf_csv

[jaki]

ysql_hba_conf tserver flag is deprecated. Use ysql_hba_conf_csv instead in the documentation. For example, change the page https://docs.yugabyte.com/latest/secure/authentication/password-authentication/.

@jaki is it used the same ? If it has changed, where can I learn about the new syntax ?

[jaki]

I'm actually not too sure about the new syntax. It worked about the same when I had tried it. I think @d-uspenskiy worked on the feature, so he can clarify.

Hi @ddorian

the rule is:

• in case filed has , or " it should be quoted with "
• the " symbol in quoted field should be doubled (i.e. "")

Example. Suppose we have two fields:
host all all 127.0.0.1/0 password
and
host all all 0.0.0.0/0 ldap ldapserver=***** ldapsearchattribute=cn ldapport=3268 ldapbinddn=***** ldapbindpasswd="*****"
Second field has the " symbol so we should quote this field and doubles the " symbol in this field
result will be
"host all all 0.0.0.0/0 ldap ldapserver=***** ldapsearchattribute=cn ldapport=3268 ldapbinddn=***** ldapbindpasswd=""*****"""

now fields can be joined with the , symbol
host all all127.0.0.1/0 password,"host all all 0.0.0.0/0 ldap ldapserver=***** ldapsearchattribute=cn ldapport=3268 ldapbinddn=***** ldapbindpasswd=""*****"""
and the final result is the using of the ' symbol to set the flag value
--ysql_hba_conf_csv='host all all 127.0.0.1/0 password,"host all all 0.0.0.0/0 ldap ldapserver=***** ldapsearchattribute=cn ldapport=3268 ldapbinddn=***** ldapbindpasswd=""*****"""'
