Snyk reported vulnerabilities

Investigate and fix the Snyk reported vulnerabilities: https://snyk.io/test/github/nearform/udaru?severity=high&severity=medium&severity=low

The fix for this would be to migrate to Hapi v17. I would actually wait for this hapijs/hoek#230 to be solved.

Thank you for the input, yes upgrading to v17 is not an option right now.

I updated lodash in my last pull request, it should sort the second Snyk issue :-)

[mcollina]

First one is resolved, Snyk would be updated shortly, last Hoek in the 4.x.x line solves the issue.

pbac updated too, in pull request... only issue here is the context stuff that @dberesford mentioned, tests seem to be passing, but we will need to investigate usage of context with variables, it might be that we're not handling correctly or testing scenarios
