introduces `tls_min_version`, `tls_max_version`, and `tls_ciphers` fields to input instances. These options are parsed during config loading and applied during TLS initialization." Signed-off-by: Eduardo Silva <[email protected]>
Adds support for `tls.min_version`, `tls.max_version`, and `tls.ciphers` in output instances. Values are parsed and enforced during TLS context setup. Signed-off-by: Eduardo Silva <[email protected]>
Adds backend API hooks `set_minmax_proto` and `set_ciphers`, and utility functions `flb_tls_set_minmax_proto()` and `flb_tls_set_ciphers()` for applying TLS constraints. Signed-off-by: Eduardo Silva <[email protected]>
Adds support for parsing TLS protocol versions and disabling specific ones using SSL options. Also enables cipher selection via `SSL_CTX_set_cipher_list()`. Signed-off-by: Eduardo Silva <[email protected]>

This PR introduces three new TLS configuration options for both input and output plugins:
tls.min_version: specifies the minimum allowed TLS version (e.g., TLSv1.1, TLSv1.2).tls.max_version: specifies the maximum allowed TLS version (e.g., TLSv1.2, TLSv1.3).tls.ciphers: allows users to define a specific set of TLS ciphers (up to TLSv1.2).The options are added to the input/output configuration map and respected during TLS context initialization. This enhances TLS flexibility and allows better control over security compliance and compatibility with external systems.
