Previously, get_ssl_configuration() created a new SSL context on every
call, even when the configuration was identical. This caused continuous
memory allocation from ssl.create_default_context(), especially during:
- Proxy server startup
- Background health checks
- HTTP client creation
Solution:
- Added _ssl_context_cache to cache SSL contexts by configuration
parameters (cafile, ssl_security_level, ssl_ecdh_curve)
- Refactored SSL context creation into _create_ssl_context() helper
- Modified get_ssl_configuration() to reuse cached contexts when
configuration matches
This significantly reduces memory allocation while maintaining backward
compatibility. SSL contexts are now reused instead of being recreated
repeatedly, eliminating the memory leak observed in memray profiling.
Fixes memory allocation issue where create_default_context was allocating
6.282MB+ continuously even without any requests.
