Revise TLS based mysql connections with php 8.2

With php 8.2, they fail. The work around is to downgrade ssl settings in /etc/ssl/openssl.cnf:

openssl_conf = openssl_init

[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
Options = UnsafeLegacyServerConnect
MinProtocol = TLSv1
CipherString = DEFAULT:@SECLEVEL=0
