Scripts packaging and distribution network

Have some infra where people can submit their BPF 'analysis script bundles' and easily access and download scripts written by other people. For example, a person willing to do an analysis can search through scripts, their descriptions, public rating, certification, number of downloads etc. We can extend it to a minimal bundle packaging system as well. There can be commands like,

```
# Install an analysis script bundle
bpf-get install syscall-latency

# Search analysis scripts
bpf-get search task-switch

# Show details about script, examples, if it's stable or testing etc.
bpf-get info task-switch

# List all analysis scripts
bpf-get --list all

# List all scripts containing 'sched_switch' tracepoint
bpf-get --list --tracepoint sched_switch

# Remove script
bpf-get remove task-switch

# Upgrade scripts
bpf-get update task-switch

# Get source files of the script bundle
bpf-get source task-switch

# Package the script directory to a BPF bundle
bpf-bundle package ./task-switch

# Submit scripts to public review pool. After certain karma threshold or
# moderator intervention we can add it to the stable distribution pool
bpf-bundle submit task-switch-0.3.bun
```

Then, run them using `bpf-run`

In the long run, we could also provide a web interface to browse different scripts and see what they do just as in https://atlas.hashicorp.com/boxes/search with the history of all the addition to the scripts. In addition, we can also show description and how a typical analysis and output would look.
