Unit 1.2 release

[Valentin V. Bartenev]

Hello,

I'm glad to announce a new release of NGINX Unit.

Changes with Unit 1.2                                            07 Jun 2018

    *) Feature: configuration of environment variables for application
       processes.

    *) Feature: customization of php.ini path.

    *) Feature: setting of individual PHP configuration options.

    *) Feature: configuration of execution arguments for Go applications.

    *) Bugfix: keep-alive connections might hang after reconfiguration.


Here's an example of new configuration parameters of application objects:

    {
        "args-example": {
            "type": "go",
            "executable": "/path/to/compiled/go/binary",
            "arguments": ["arg1", "arg2", "arg3"]
        },

        "opts-example": {
            "type": "php",
            "root": "/www/site",
            "script": "phpinfo.php",

            "options": {
                "file": "/path/to/php.ini",
                "admin": {
                    "memory_limit": "256M",
                    "variables_order": "EGPCS",
                    "short_open_tag": "1"
                },
                "user": {
                    "display_errors": "0"
                }
            }
        },

        "env-example": {
            "type": "python",
            "path": "/www/django",
            "module": "wsgi",

            "environment": {
                "DB_ENGINE": "django.db.backends.postgresql_psycopg2",
                "DB_NAME": "mydb",
                "DB_HOST": "127.0.0.1"
            }
        }
    }

Please note that "environment" can be configured for any type of application.
