v1.26.0 release

Release of:

• opentelemetry-api
• opentelemetry-sdk
• exporter packages

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.
