feature flags (#1933)
Package fflag provides a simple feature flag system.

 Feature names are lowercase and can only contain letters, numbers, undercores
 and dots.

 good: "foo", "foo_bar", "foo.bar"
 bad: "Foo", "foo-bar"

 A feature flag can be enabled by the user with an environment variable
 or by adding it to {ConfigDir}/feature.yaml

 I.e. CROWDSEC_FEATURE_FOO_BAR=true
 or in feature.yaml:
```
 ---
 - foo_bar
```

 If the variable is set to false, the feature can still be enabled
 in feature.yaml. Features cannot be disabled in the file.

 A feature flag can be deprecated or retired. A deprecated feature flag is
 still accepted but a warning is logged. A retired feature flag is ignored
 and an error is logged.

 A specific deprecation message is used to inform the user of the behavior
 that has been decided when the flag is/was finally retired.
