Enhance Temporal Connection Configuration with SSL Support and Flexibility

[butschster]

This PR introduces the ability to configure multiple connections to Temporal servers, including SSL-enabled connections. It aims to provide greater flexibility and security in connection setup, improving upon the previous single-address configuration approach.

What was changed

• Added support for defining multiple connection options, including SSL configurations, in a structured array format.
• Introduced secure connection config including Temporal Cloud.
• Enabled dynamic connection selection based on environment variables.
• The previous methods address, clientOptions, temporalNamespace still work, but a deprecation warning will be issued.
• Added ability to configure the default client context.

Previous Configuration:

<?php

return [
   'address' => env('TEMPORAL_ADDRESS', '127.0.0.1:7233'),
];

**New Configuration:

<?php

use Spiral\TemporalBridge\Config\ClientConfig;
use Spiral\TemporalBridge\Config\ConnectionConfig;

return [
    'client' => env('TEMPORAL_CONNECTION', 'default'),
    'clients' => [
        'default' => new ClientConfig(
            connection: new ConnectionConfig('localhost:7233')
        ),
        'secure' => new ClientConfig(
            connection: new ConnectionConfig(
                address: 'localhost:7233',
                tlsConfig: new TlsConfig(
                    privateKey: '/my-project.key',
                    certChain: '/my-project.pem',
                ),
            ),
            options: (new ClientOptions())
                ->withNamespace('default'),
            context: Context::default()
                ->withTimeout(4.5)
                ->withRetryOptions(
                    RpcRetryOptions::new()
                        ->withMaximumAttempts(5)
                        ->withInitialInterval(3)
                        ->withMaximumInterval(10)
                        ->withBackoffCoefficient(1.6)
                ),
            ),
        ),
    ],
];
