d037f9a9a4 Use new user scripts config and gui 
The user scripts configuration can now be configured from the "User Scripts" entry under the cog
icon. It allows the creation of multiple configuration presets to be applied to hosts, networks and
interfaces.

139a16ffe3 Fix protocol categories association lost after reboot 
After the recent changes, there is only one global nDPI struct which
is share across all the interfaces. However, the struct can be swapped
during normal operating, so it's necessary to reload the associations
every time a new nDPI struct is allocated.

Fixes #3139

a3432e00e8 Implement ntopng plugins 
Plugins are a convenient way to group together related lua scripts.
Their primary use case is to group user scripts and their alert/status
definition.
The builtin ntopng user scripts and definitions are now
packed into plugins directories. In future, we will support loading of
user created plugins.
Plugins are loaded at startup into some runtime directories and then
used. Other changes provided by this commit include:

- Add sample flow logger plugin
- Initial support for system user scripts
- Rename edge to threshold
- Migrate system probes to user scripts/plugins
- Migrate scripts to more explicit alerts_api.checkThresholdAlert api

0d48bff069 Implement more flexible user_scripts api 
NOTE: The existing alerts configuration of the users will be discarded.

Some code has been added to make the current gui on/off toggle work.
It is marked with the following comment:

-- TODO remove after implementing the new gui

df0556cb87 Optimize flow alerts generation 
This provides a ~10x speedup by performing the JSON serialization work in C
(and thus avoiding Lua->C overhead). This also implements two in-memory alerts
queues (one for sqlite and one for the notifications) in order to reduce Redis load.
Alerts queue are now global instead of per-interface as there is only 1 dequeing thread.

redis load is reduced and design is simpler.
