Set the global or per-subject compatibility levels.

Running this command without a subject sets the global compatibility level. To set the global level at the same time as per-subject levels, use the `--global` flag.

LEVELS:

-   BACKWARD (`default`): Consumers using the new schema (for example, version 10) can read data from producers using the previous schema (for example, version 9).

-   `BACKWARD_TRANSITIVE`: Consumers using the new schema (for example, version . can read data from producers using all previous schemas (for example, versions 1-9).

-   `FORWARD`: Consumers using the previous schema (for example, version 9) can read data from producers using the new schema (for example, version 10).

-   `FORWARD_TRANSITIVE`: Consumers using any previous schema (for example, versions 1-9) can read data from producers using the new schema (for example, version 10).

-   `FULL`: A new schema and the previous schema (for example, versions 10 and 9) are both backward and forward compatible with each other.

-   `FULL_TRANSITIVE`: Each schema is both backward and forward compatible with all registered schemas.

-   `NONE`: No schema compatibility checks are done.
