Breaking changes

[SECURITY] Remove OTLP HTTP support for TLS 1.0 and TLS 1.1, require TLS 1.2 or better #2722
- The OTLP HTTP exporter no longer accept options like:
  - min_TLS = 1.0
  - min_TLS = 1.1
  - max_TLS = 1.0
  - max_TLS = 1.1
- When connecting to an OTLP HTTP endpoint, using https, the connection will require TLS 1.2 by default, unless min_TLS is set to 1.3
- Plain http connections (insecure) are not affected.
