Support php.ini feature

[tillkruss]

It looks like we might be able to use our own relay.ini file contents and instruct PIE to put it in place without creating a extension = relay.so in the main php.ini.

php/pie#155

• priority

@tillkruss unfortunately pie doesn't allow to put our own ini file

[tillkruss]

I think they just added it in the last release, did they not?

[yatsukhnenko]

They added code to automatically enable extension by adding entry to php.ini or separate file ini, but it doesn't allow to set custom content

I see. Can we give PhpRedis the priority 60 and Relay 70 for PIE?
