wish to add two functions to IMUNES (MANET & Docker images selection)

Dear IMUNES developers,

I hope you to add two functions to IMUNES (MANET & Docker images selection)

first, to support MANET, similar to CORE.

Second, can select one docker image in a node, similar to CORE.

this is the same to https://github.com/imunes/imunes/issues/52

Best regards,
Tongguang Zhang
