Need option to Create Lambda functions

[raj-wankhede-github]

Need an option to also create lambda functions if it does not exists. Currently only existing Lambda functions can be updated, and if function does not exists, we get below response:
{
RespMetadata: {
StatusCode: 404,
RequestID: "1234-12345-40gg-f123-1234"
},
Message_: "Function not found: arn:aws:lambda:::function:",
Type: "User"
}
