// that if two files specify a "red-user", only values from the first file's red-user are used. Even
// non-conflicting entries from the second file's "red-user" are discarded.
// 2. Determine the context to use based on the first hit in this chain
// 1. command line argument - again, parsed from the command line, so it must be late bound
// 2. CurrentContext from the merged kubeconfig file
// 3. Empty is allowed at this stage
// 3. Determine the cluster info and auth info to use. At this point, we may or may not have a context. They
// are built based on the first hit in this chain. (run it twice, once for auth, once for cluster)
// 1. command line argument
// 2. If context is present, then use the context value
// 3. Empty is allowed
// 4. Determine the actual cluster info to use. At this point, we may or may not have a cluster info. Build

// 1. command line argument
// 2. If cluster info is present and a value for the attribute is present, use it.
// 3. If you don't have a server location, bail.

// technique per auth info. The following conditions result in an error:
// 1. If there are two conflicting techniques specified from the command line, fail.

// 1. Merge together the kubeconfig itself. This is done with the following hierarchy and merge rules:
// 1. CommandLineLocation - this parsed from the command line, so it must be late bound
// 2. EnvVarLocation
// 3. CurrentDirectoryLocation
// 4. HomeDirectoryLocation
// Empty filenames are ignored. Files with non-deserializable content produced errors.
// The first file to set a particular value or map key wins and the value or map key is never changed.
// This means that the first file to set CurrentContext will have its context preserved. It also means
// that if two files specify a "red-user", only values from the first file's red-user are used. Even
// non-conflicting entries from the second file's "red-user" are discarded.
// 2. Determine the context to use based on the first hit in this chain
// 1. command line argument - again, parsed from the command line, so it must be late bound
// 2. CurrentContext from the merged kubeconfig file
// 3. Empty is allowed at this stage
// 3. Determine the cluster info and auth info to use. At this point, we may or may not have a context. They
// are built based on the first hit in this chain. (run it twice, once for auth, once for cluster)
// 1. command line argument
// 2. If context is present, then use the context value
// 3. Empty is allowed
// 4. Determine the actual cluster info to use. At this point, we may or may not have a cluster info. Build
// each piece of the cluster info based on the chain:
// 1. command line argument
// 2. If cluster info is present and a value for the attribute is present, use it.
// 3. If you don't have a server location, bail.
// 5. Auth info is build using the same rules as cluster info, EXCEPT that you can only have one authentication
// technique per auth info. The following conditions result in an error:
// 1. If there are two conflicting techniques specified from the command line, fail.
// 2. If the command line does not specify one, and the auth info has conflicting techniques, fail.
// 3. If the command line specifies one and the auth info specifies another, honor the command line technique.
