Additional Default Timer Options for Compliance Network Intents

NetBrain currently offers a limited set of default timer intervals for scheduling Network Intent execution, which does not include options aligned to common compliance review cycles. This enhancement would add additional default timer options, such as weekly, monthly, and quarterly intervals, so that compliance-focused Network Intents can be scheduled without requiring custom timer configuration. Customers running periodic configuration compliance checks would benefit from ready-to-use scheduling options that match standard reporting and audit cycles, reducing setup effort and ensuring consistent execution timing.
