The REST API has no writable config endpoint for SNMP communities.
When _action_fix_snmp() is called on a REST-connected driver, it now
opens a temporary Netmiko SSH session (standard KEX, then legacy KEX
fallback), runs the config-mode CLI commands, and restores the REST
transport state on exit. SSH errors are surfaced verbatim instead of
being silently swallowed.
Also:
- _save_config: guard against REST transport (was calling self._device
directly → NoneType AttributeError when transport == "api")
- _action_fix_snmp: extracted CLI logic into _action_fix_snmp_cli()
so it is reused for both the SSH-fallback and native SSH/Telnet paths
- api_client: add get_snmp_communities() + configure_snmp_community()
for future use; improve GET error logging (warn vs debug on non-404)
- _try_api: probe timeout capped at 15 s; SSL retry loop for
self-signed certificates; improved log levels
- _api_set_interface / _cli_set_interface: handle enabled/description
fields that were previously ignored
- probe(): broaden accepted status codes (301/302/303/403)
