MINOR: httpclient: complete the https log

The httpsclient_log_format variable lacks a few values in the TLS fields
that are now available as fetches.

On the backend side we have:

"%[fc_err]/%[ssl_fc_err,hex]/%[ssl_c_err]/%[ssl_c_ca_err]/%[ssl_fc_is_resumed] %[ssl_fc_sni]/%sslv/%sslc"

We now have enough sample fetches to have this equivalent in the
httpclient:

"%[bc_err]/%[ssl_bc_err,hex]/%[ssl_c_err]/%[ssl_c_ca_err]/%[ssl_bc_is_resumed] %[ssl_bc_sni]/%[ssl_bc_protocol]/%[ssl_bc_cipher]"

Instead of the current:

"%[bc_err]/%[ssl_bc_err,hex]/-/-/%[ssl_bc_is_resumed] -/-/-"
