fix: set CANISTER_CANDID_PATH_<canister name> properly for remote canisters

In the remote canister declaration it is possible to set a candid file to use when the canister is remote on a specific network.
dfx now correctly sets the CANISTER_CANDID_PATH_<canister name> environment variable during the build process on remote networks if the file exists.

feat: display schema for dfx metadata json

dfx schema --for dfx-metadata to display JSON schema of the "dfx" metadata.

feat: add tech_stack to the Canister Metadata Standard

The standardized dfx metadata is extended with another object: tech_stack.

Please check tech-stack for more details.

chore: updated management canister .did file

feat: added dfx completion command

This command generates shell completion scripts for bash, elvish, fish, zsh, or PowerShell.

Describing how to install shell completion scripts is beyond the scope of this document.
Here are two commands that would enable command completion in the current shell:

In zsh:

source <(dfx completion zsh)

In bash:

source <(dfx completion)

fix: dfx no longer always creates .dfx directory if dfx.json is present

Previously, dfx would always create a .dfx directory in the project root if dfx.json was present.
Now, it only does so if the command accesses the .dfx directory in some way.

fix: dfx only loads dfx.json for commands that need it

For example, this will work now:

echo garbage >dfx.json && dfx identity get-principal
