feat: Support for connecting existing directory to an existing Micro

[Andrei Jiroh Halili]

Suggestion

Have some sort of connect command in the CLI to seamlessly connect existing directory to an existing Micro without pain.

Workarounds

Currently, the only workaround is copy the contents of $PWD/.deta/prog_info file to the target machine or even set it as an secret in CI settings and do some "echo $DETA_PROG_INFO > .deta/prog_info`.
