feat: support disable resource periodically sync

[lingsamuel]

• Bugfix
• New feature provided
• Improve performance

What this PR does / why we need it:

The function can be useless if the user has never messed up ingress controller managed resources in APISIX. It should be able to be disabled.

Also, the default value 5m is too small. Every sync writes to etcd, causing etcd to store too many history records, making the dbsize grow dramatically over time.

(also fixes a small problem, defer shouldn't in loop)
