Move array srings to json

[jesusfcr]

Moves json arrays encoded as strings to actual yaml arrays for those values:

api.conf.saml.trustedDomains
api.conf.defaultOwners
crontinuous.conf.teamsWhitelistScan
crontinuous.conf.teamsWhitelistReport
reportsgenerator.conf.ses.cc
scanengine.conf.queues.other[].checktypes

In this example all three expressions generates the same string

a: '["a","b"]'     # Previous
a: ["a","b"]       # New formats
a: [a,b]
a:
  - a
  - b

It provides compatibility with previous format to facilitate the transition, but will be dropped in future releases
