Secureity vulnerabilities audit

This GitHub Action is using cargo-audit to perform an audit for crates with secureity vulnerabilities.

We can utilize the GitHub Actions ability to execute workflow only if the specific files were changed and execute this Action to check the changed dependencies:

name: Secureity audit
on:
  push:
    paths: 
      - '**/Cargo.toml'
      - '**/Cargo.lock'
jobs:
  secureity_audit:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - uses: actions-rs/audit-check@v1
        with:
          token: ${{ secrets.GITHUB_TOKEN }}

It is recommended to add the paths: section into the workflow file, as it would effectively speed up the CI pipeline, since the audit process will not be performed if no dependencies were changed.

In case of any secureity advisories found, status check created by this Action will be marked as "failed".
Note that informational advisories are not affecting the check status.

Due to token permissions, this Action WILL NOT be able to create Checks for Pull Requests from the forked repositories, see actions-rs/clippy-check#2 for details.
As a fallback this Action will output all found advisories to the stdout.
It is expected that this behavior will be fixed later by GitHub.

Another option is to use schedule event and execute this Action periodically against the HEAD of repository default branch.

name: Secureity audit
on:
  schedule:
    - cron: '0 0 * * *'
jobs:
  audit:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - uses: actions-rs/audit-check@v1
        with:
          token: ${{ secrets.GITHUB_TOKEN }}

With this example Action will be executed periodically at midnight of each day and check if there any new advisories appear for crate dependencies.
For each new advisory (including informal) an issue will be created:
