adds DNS and websites deployment commands

[peterjah]

Need:
Two new commands

1. Set en DNS entry:

   examples:
   npx @massalabs/sc-toolkit dns --set toto.massa
   optionnal flags:
   --rpc
   --dnsAddress
   --privateKey (?)

2. Deploy website:

   examples:
   npx @massalabs/sc-toolkit deployWebsite mywebsite.zip
   optionnal flags:
   --rpc
   --dnsAddress
   --privateKey (?)

For private key, several possibilities:

• pass it as flag arg
• read in .env file
• read exported data from Thyra (possible? with password?)

dependencies:
All these features uses the smart contract deployer. in order to do clean stuffs we have to factorize this.
There is already a big part of the work which is already done here: https://github.com/massalabs/massa-sc-utils
We should use it, and adapt for our needs. This should also be nice to add a command line feature for these tools
(i.e npx massa-utils deploy mycontract.wasm") to be use in npm script "deploy": "massa-utils deploy"

We need to clarify the difference between deploying a SC directly and deploying a SC through a deployment contract.
It will be good to decide of an appropriate wording about this

brainstorming option names for the 'deploy through a deployer smarcontract' use case:
--generate-deployer
--deploy-function
--createSC

I propose to generalize the use of typescript. (vanilla javascript forbidden) @massalabs/massa-sc-utils is already a typescript module

@peterjah can you give me a bit more context on this one? What is the use-case for a sc-developer who uses the sc-initializer?

[peterjah]

Its not for SC builders only, but anyone who wants to add a DNS entry or upload a website using command line instead of Thyra.
