Ignore metadata "time"

[w1mvy]

Description

When use Elixir 1.10 and GoogleCloudLogging Formatter, logger_json's millseconds "time" value be overwritten by metadata microseconds "time". According to the documentation, logger_json be expected "time" value is milliseconds. So, Made a change to add "time" to ignored_metadata_keys.

Fixed: #49

Basic Formatter

%{"message" => "hello", "metadata" => %{"domain" => ["elixir"], "dynamic_metadata" => 5, "time" => 1596772387300756, "user_id" => 11}, "severity" => "debug", "time" => "2020-08-07T12:53:07.302Z"}

GoogleCloudLogging Formatter

%{"domain" => ["elixir"], "logging.googleapis.com/sourceLocation" => %{"file" => "/Users/w1mvy/ghq/github.com/Nebo15/logger_json/test/unit/logger_
json_google_test.exs", "function" => "Elixir.LoggerJSONGoogleTest.test logs binary messages/1", "line" => 59}, "message" => "hello", "severity" => "DEBUG", "time" => 1596772397130034}

After
