Use url-safe characters in falco version

In some cases, you might want to host falco packages in a way where
they're directly accessible via http. The '+' character that separates
the version and the git hash ends up breaking naive solutions that don't
properly url-escape the package name before doing the http fetch.

Of course, clients can properly url-escape, but switching to a tilde is
url safe and I think still preserves the idea of separating the version
and hash.

The Logz.io platform consists of three products — Log Management, Infrastructure Monitoring, and Cloud SIEM — that work together to unify the jobs of monitoring, troubleshooting, and security. We empower engineers to deliver better software by offering the world's most popular open source observability tools — the ELK Stack, Grafana, and Jaeger — in a single, easy to use, and powerful platform purpose-built for monitoring distributed cloud environments. Cloud SIEM supports data from multiple sources, including Falco's alerts, and offers useful rules and dashboards content to visualize and manage incidents across your systems in a unified UI.

We build CI/CD pipelines the GitOps way, as well as design and run k8s clusters.

 * [Swissblock Technologies](https://swissblock.net/) At Swissblock we connect the dots by combining cutting-edge algorithmic trading strategies with in-depth market analysis. We route all Falco events to our control systems, both monitoring and logging. Being able to deeply analyse alerts, we can understand what is running on our Kubernetes clusters and check against security policies, specifically defined for each workload. A set of alarms notifies us in case of critical events, letting us react fast. In the near future we plan to build a little application to route Kubernetes internal events directly to Falco, fully leveraging Falco PodSecurityPolicies analyses.

Traditional FIM solutions were not scalable and not working for our environment, but with Falco we found the solution we needed. Falco's detection capabilities have helped us identify anomalous behaviour within our clusters. We leverage Sidekick (https://github.com/falcosecurity/charts/tree/master/falcosidekick) to send Falco alerts to a PubSub which in turn publishes those alerts to our SIEM (SumoLogic)

 * [Sysdig](https://www.sysdig.com/) Sysdig originally created Falco in 2016 to detect unexpected or suspicious activity using a rules engine on top of the data that comes from the sysdig kernel system call probe. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended Falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-defined infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.
