Assignment of a configuration to the agent based on the properties

[tingrida]

As an IT operator, I want to be able to assign a configuration based on properties to multiple agents to ensure fast and stable instrumentation of multiple agents.

Use Cases:

• All agents from the services in stage P need to get a specific configuration for instrumentation.
• All agents of the services with Apache CXF Library must have a specific configuration for instrumentation.
• All agents from the services with a specific Java version must have a specific configuration for instrumentation.

Out of scope: conflicts, priority.

Acceptance criteria:

• In the config-server API, it is possible to define a subgroup of agents based on their properties.
• In the config-server API, it is possible to define a subgroup of configurations based on their properties.
• In the config-server API, it is possible to assign a subgroup of configurations to a subgroup of agents.
