blackfire connection errors in the log file

My log file is polluted with these errors:

I do not use blackfire so I do not pass it to docker-compose up, but it should not be mandatory (or if it is it should be setup by default).

We probably need to dynamically enabled/disable the php module during container start 👍

[come-nc]

Workaround: docker exec /nextcloud_nextcloud_1 rm /usr/local/etc/php/conf.d/blackfire.ini

[juliusknorr]

I'd say we can have it disabled by default and add a script in https://github.com/juliushaertl/nextcloud-docker-dev/tree/master/scripts to enable/disable by commenting out the content of blackfire.ini

[juliusknorr]

Blackfire and xdebug are now disabled by default and can be turned on if required as described in #104 (comment)
