In our hot-reloading context handling, there is a possibility not to able to handle hot-reloading correctly. For this case, we should treat as error and halt the process. Signed-off-by: Hiroshi Hatake <hatake@calyptia.com>

On hot-reloading, we intended to keep fluent-bit process as much as possible when an error is included in the loaded configuration file.
However, the current behavior is not ideal for containing invalid values for provided valid parameters in the configuration file during hot-reloading. This PR is mainly for filter_lua case which is loaded invalid lua script as described in #8067.
In this situation, we should validate malformed values especially for Lua script.
In filter_lua, fluent-bit isn't able to process events when loading an invalid Lua script. This should be halted for hot-reloading process.
