Schema functionality missing

[polyzos]

Currently we can set the schema compatibility strategy as well as allow auto update schema doing the following using the pulsar-admin tool

./pulsar-admin namespaces set-schema-compatibility-strategy -c FORWARD_TRANSITIVE public/default
./pulsar-admin namespaces set-is-allow-auto-update-schema --disable public/default

Seems like the set-is-allow-auto-update-schema is missing from the terraform modules at the moment, so we need to support this as well.

Currently, the pulsarctl doesn't support the namespaces set-is-allow-auto-update-schema feature, I need some times support this.
