Add headers as optional params while invalidating/refreshing

[calumbrodie]

As discussed in FriendsOfSymfony/FOSHttpCache#117

Depends on FriendsOfSymfony/FOSHttpCache#119

[dbu]

we should do a similar note here as ddboer did in the other PR, linking to http://foshttpcachebundle.readthedocs.org/en/latest/reference/configuration/proxy-client.html#custom-guzzle-client

thanks!
it seems you missed some tests, look at the travis failures.

can you also do a PR on https://github.com/FriendsOfSymfony/FOSHttpCache/blob/master/src/CacheInvalidator.php invalidatePath and invalidateTags ?

[dbu]

you did not implement this yet, its on the FOSHttpCache library, not the bundle...

PR now submitted to FOSHttpCache bundle

[calumbrodie]

Hi, I implemented it last night and will make a separate PR for it just now (that's why the Scrutinizer test are failing too):

Edit: FriendsOfSymfony/FOSHttpCache#119

[calumbrodie]

Edit: Scrutinizer will continue to fail until the dependencies are brought into line. I moved the dependency on HttpCache to use the new SHA instead of tag alpha-3, but reverted that as I'm unsure how you want to handle the updating of dependencies (its not really my place to make that change?)

[dbu]

looks good. in terms of php its not an error to call the method with an extra parameter, so lets leave composer.json

once the library 1.0.0 is tagged, we will update composer.json on the bundle to ask for 1.0.0
