Added HAProxy CLI commands that allow runtime inspection and modification of OTel filter settings without requiring a configuration reload. The new cli.c module registers CLI keywords under the "otel" prefix and implements the following commands: flt_otel_cli_parse_status() displays a comprehensive status report of all OTel filter instances including filter ID, proxy, disabled state, hard-error mode, logging state, rate limit, analyzer bits, and SDK diagnostic message count; flt_otel_cli_parse_disabled() enables or disables filtering across all instances; flt_otel_cli_parse_option() toggles the hard-error mode that controls whether errors disable the filter for a stream or are silently ignored; flt_otel_cli_parse_logging() manages the logging state with support for off, on, and dontlog-normal modes; flt_otel_cli_parse_rate() adjusts the sampling rate limit as a floating-point percentage; and flt_otel_cli_parse_debug() sets the debug verbosity level in debug builds. All modifications are applied atomically across every OTel filter instance in every proxy. The CLI initialization is called from flt_otel_ops_init() during filter startup via flt_otel_cli_init(), which registers the keyword table through cli_register_kw(). Supporting changes include the FLT_OTEL_U32_FLOAT macro for converting the internal uint32_t rate representation to a human-readable percentage, the FLT_OTEL_PROXIES_LIST_START/END iteration macros for traversing all OTel filter instances across the proxy list, and flt_otel_filters_dump() for debug logging of filter instances.
