// BluetoothPeerChameleondConfig is the format of the btpeer chameleond config
// JSON file stored in GCS that contains configuration information which maps
// different chameleond bundles to use for btpeers to DUT release versions.
//
// All available chameleond bundles are specified in bundles. The "next" bundle
// is only used by a smaller set of hosts whose test results are monitored to
// check whether or not this next bundle is good to release to all other
// testbeds. The next bundle is identified by the next_chameleond_commit, which
// will match its chameleond_commit.
//
// When the primary DUT's hostname is in next_dut_hosts AND its release version
// is in next_dut_release_versions, the next bundle should be used if
// next_chameleond_commit is set. Otherwise, the bundle with the the highest
// min_dut_release_version that is less than or equal to the testbed's primary
// DUT's release version (excluding the next bundle) should be used. If all
// bundles have a higher min_dut_release_version than the primary DUT, the
// bundle with the lowest min_dut_release_version (excluding the next bundle)
// should be used.
//
// For example, let's say we have the following config:
// {
//   "nextChameleondCommit": "8e331c7",
//   "nextDutHosts": [
//     "chromeos15-row8-metro4-host5",

//     "chromeos15-row5-rack7-host7",
//     "chromeos15-row5-rack8-host7",
//     "chromeos15-row5-rack1-host4",
//     "chromeos15-row5-rack2-host4"
//   ],
//   "nextDutReleaseVersions": [
//     "14051.0.0"
//   ],
//   "bundles": [
//     {
//       "chameleondCommit": "723e87b",
//       "archivePath": "gs://chromeos-connectivity-test-artifacts/btpeer/chameleond/chameleond-0.0.2-723e87b.tar.gz",
