Made priorities configurable

[rdohms]

In order to allow users to move the listeners in their priorities queue
the value is now configurable via configuration parameters. In order to
maintain BC these values default to 0 which is the current value.

this closes #49.

[rdohms]

Worth noting, I added each parameter as a scalar node to avoid adding complexity to the Extension, but i'm happy to make it an array node and extend the extension if desired..

[rdohms]

Fixed the extra line left behind, oops.

First, thanks for the PR!
IMHO, an array with fixed keys would be more elegant. Something like this:

listener_priorities:
    request: 0
    kernel_exception: 0
    console_exception: 0

Is it too much complicated do be done?

[rdohms]

@Jean85 should not be, i had done it initially. I'll add some more complexity to the extension but should be good. Gimme a sec.

[rdohms]

@Jean85 there you go. I tried to go with making the sentry.listener_priorities parameter an array and then using Symfony expressions in the services.yml file, but that has proven to not be supported in the priority section.

So i went with the simple approach of making each a scalar parameter, making config nice and clean and leaving the rest hidden behind the bundle wall.

Let me know if this needs cleaning up more, i decided to not exclude the sentry.listener_priorities, but for no strong reason at all.

Thanks, it's perfect! 👍
I'll work on the release ASAP
