2.0.0

Breaking changes:

1. Configuration file syntax has changed. bearerToken has been replaced with serviceProviderToken, and API library scopes have been adjusted accordingly. CLI package is still working account-scoped.
2. Snapshots of v1 are not compatible with the snapshots of v2. There's discrepancy between handling of LCRs.
3. "set token" command has been removed.
4. Project init no longer accepts JWT as token.

Improvements:

1. Project init: Snap encryption key is verified to be a valid base64 string.
2. Project init: Can select service provider / account to work with based on serviceProviderToken.
3. Can inspect the content of snapshot via "snapshot inspect" command.
