Option not to load url rules on bootstrap

[SDKiller]

Cuurently Podium appends its url rules on bootstrap

https://github.com/bizley/yii2-podium/blob/master/src/Podium.php#L214

This has 2 drawbacks:

1. possible undesired order of url rules (application-wide - consider that there are other modules and their corresponding rules)
2. not a trivial task of customizing Podium rules

IMO there could be a config option to load default rules as it is done now or switch off this bootstrap task and define Podium url rules in application config.

It's true especially for 2. The first one should be collision free because of the custom name you can set for the module. Still, option to shut it off sounds good.

The first one should be collision free

I talk not about name collisions, but cases when you desire to set rules order explicitly - what should be checked first and what last. Maybe you have some "fallback" rules in the end to catch other requests.

Podium rules are appended.
