As a Korifi API user I want to be able to list security groups

[danail-branekov]

Acceptance

GIVEN I have deployed Korifi with experimental.securityGroups.enabled=true value
GIVEN I have created a security group
WHEN I list security groups via GET /v3/security_groups
THEN I get a list of existing security groups
WHEN I list security groups with a name filter via GET /v3/security_groups?names=my-sg&page=1&per_page=1
THEN I get a list containing the security group with that name

Dev notes

• We need to implement filtering by names as this is one of the requests the CLI sends when running cf bind-running-security-group
• We need to implement filtering by globally_enabled_staging=true as this is what staging-security-groups invokes
• We need to implement filtering by globally_running_staging=true as this is what running-security-groups invokes
• The rest of the filters could be out of scope for this story, we could add them as a follow up one, or implement them here if trivial
• When this story is done, security-group, security-groups, staging-security-groups and running-security-groups commands should work, so corresponding smoke tests should be added to the suite
