* enable timeout for http transports
Attempt to do our own discovery for some well-known PSR-18 clients, which allows
for configuring timeout (and in future certificates, keys etc).
This is not complete and a prototype for feedback, but I've updated an example to
show that it works for Guzzle and Symfony http clients
* improve client discovery
* refactor, test, add more implementations
* add timeout for logs and metrics
send errors/warnings/etc by default through PHP's error_log. This gives more control to administrators, since error_log can
be configured to write to any stream (file, stderr, etc). I think it's also less surprising for people trying out otel (particularly
with development PHP settings, where trigger_error often breaks an application).
Adding a configuration value to control where logs go: OTEL_PHP_LOG_DESTINATION.
- apply TC review feedback to move Globals to top-level.
it was suggested to move Instrumentation into its own package, but I chose instead to just move that dir
up to the top level of API
- added a BC layer to alias the moved classes
- added some more examples
* implement bridge api
* adding logs memory exporter
* clarify bridge api not for developers
* adding logger provider builder
* review feedback
* removing Bridge and documenting what a bridge is
* adding exporter + transport registry
to remove the hidden dependency between SDK and contrib, move all of the exporter knowledge out of
exporter factory, and invent a registry to hold those values. The registry can be added to by contrib
modules as part of composer autoloading.
This also allows users to override things like transports (eg, provide their own grpc transport).
Remove exporter's fromConnectionString as it's not in spec, and I couldn't get it to work nicely with the
registry idea.
* fixing up examples
* allow callables to be registered as factories
adding an example of replacing a registered transport factory with another implementation
* Registry to FactoryRegistry
* new relic exporter factory, tests
* review suggestions
* tidy
* change fromEnvironment() to create() in factories
