ssl_min/max_ver, pre_start_script, config_mode raw_blocks_only, raw_blocks without names

[kinjelom]

1. ssl_min_ver and ssl_max_ver: These settings enforce minimum and maximum SSL versions for connections. If this option is set, the disable_tls_* options will be ignored.

2. pre_start_script: A script appended to the pre-start script of HAProxy job. This script allows the job to prepare the machine before starting HAProxy, for example, by setting the MTU to a custom value.

3. config_mode: This includes two modes:

   • 'auto': default, utilizes raw_config if defined; otherwise, it uses traditional configuration mixed with raw_blocks.
   • 'raw_blocks_only': uses only raw_blocks, ignoring other configurations.

4. support for raw_blocks with or without names, this is more readable for blocks global and defaults, especially when applying the setting config_mode=raw_blocks_only.
