Add configurable limits for SEP, MRAP and VMP policies

What does this MR do and why?

This MR adds configurable limits for three types of security policies:

• Scan Execution Policies (SEP)
• Security Approval Policies (MRAP)
• Vulnerability Management Policies (VMP)

Previously, only Pipeline Execution Policies had configurable limits, while the other policy types had hard-coded limits. This change allows administrators to configure limits for all policy types at both the instance and group levels, providing more flexibility and control over security policy usage.

Implementation details:

• Added new configurable limits in application settings for all policy types
• Extended the LimitService to handle limits for all policy types
• Removed hard-coded constants (POLICY_LIMIT) in favor of dynamic limits
• Added UI controls in admin settings and group settings to manage these limits
• Added proper validations for all new limit settings

Benefits:

• Administrators can now customize limits based on their organization's needs
• Consistent approach for all policy types
• Better resource management for large organizations
• Improved flexibility for different deployment scenarios

References

• Related to the ongoing effort to make security policy limits more configurable
• Extends the existing functionality for Pipeline Execution Policies to other policy types

How to set up and validate locally

1. Access the Admin Area > Settings > Security Policies
2. Configure the new limit settings for each policy type
3. Create or edit a group to set group-specific limits
