Prepare v0.69.0 (#1114)

## Google Cloud PHP v0.69.0

### google/cloud-debugger v0.12.0

* Cloud Debugger limits the amount of data captured for snapshots by default. Several new configuration options have been added to {@see Google\Cloud\Debugger\Agent::__construct()} to allow control over these new defaults. (#1099)
* Fixed a bug where a debuggee may not register properly. (#1102)
* Fixed a bug where Stackdriver Debugger was not compatible with PHP 7.0. (#1104)

### google/cloud-logging v1.12.1

* Added missing passthrough options in {@see Google\Cloud\Logging\LoggingClient::psrLogger()} and fixed object serialization. (#1110)

### google/cloud-videointelligence v1.0.0

* There are no code changes since our last release, but we are proud to now announce our support of Cloud Video Intelligence at a GA level. This means that we do not expect to introduce any breaking changes and that we believe the library is ready for production use.
