Important changes


[SDK] Swap Tracer/Meter/LoggerConfig disabled for enabled

#3942

In TracerConfig(bool), MeterConfig(bool), and LoggerConfig(bool),

the boolean parameter now represents enabled instead of disabled.
User code calling these constructors explicitly must be adjusted

to pass false to disable.



[BUILD] Revisit EventLogger deprecation

#3855

File DEPRECATED.md contains information about current deprecation

plans.
Please adjust your application accordingly, to avoid disruption.



[CONFIGURATION] File configuration - spec stability

#3862

The specification for declarative configuration is now stable.
As a result, environment variable OTEL_EXPERIMENTAL_CONFIG_FILE

is now renamed to OTEL_CONFIG_FILE.
