Missing logger

- Algolia Client Version: latest

### Description

On the Algolia PHP Client, there is the logger feature that allow us to log what happens when a `search`|or other method is called. By default, there is a debug logger that will `print` the requests that are made by the client:
```php
Algolia\AlgoliaSearch\Logger\DebugLogger::enable();

$index->search('foo'); // Dumps information about the request on the console.

Algolia\AlgoliaSearch\Logger\DebugLogger::disable();
```

Example output on the console:
```
array:3 [
"level" => "debug"
"message" => "Algolia API client: Sending request."
"context" => array:6 [
"body" => array:1 [
"query" => "fo"
]
"headers" => array:4 [
"X-Algolia-Application-Id" => ".."
"X-Algolia-API-Key" => ".."
"User-Agent" => "Algolia for PHP (2.2.6); PHP (7.3.5)"
"Content-Type" => "application/json"
]
"method" => "POST"
"query" => []
"retryNumber" => 1
"host" => "https://..-dsn.algolia.net/1/indexes/contacts/query"
]
]
array:3 [
"level" => "debug"
"message" => "Algolia API client: Host failed."
"context" => array:7 [
"body" => array:1 [
"query" => "fo"
]
"headers" => array:4 [
"X-Algolia-Application-Id" => ".."
"X-Algolia-API-Key" => ".."
"User-Agent" => "Algolia for PHP (2.2.6); PHP (7.3.5)"
"Content-Type" => "application/json"
]
"method" => "POST"
"query" => []
"retryNumber" => 1
"host" => "https://..-dsn.algolia.net/1/indexes/contacts/query"
"description" => "An internal server error occurred on ..-dsn.algolia.net"
]
]
```

This issue addresses that feature, as we don't have a logger on the python client. The idea, would be inject a concrete implementation of the logger on the client, allowing people to use this logger for debug purposes, but also, eventually for production reasons using their own specific logger.
