Describe the feature you'd like

The Infinity HTTP API already provides the show command to display the status of the infinity internal database. However, there is no way to access the configuration and variables within the system. The goal of this PR is to propose a couple of HTTP APIs to accomplish this.

• Show variables

curl --request GET \
     --url localhost:23820/variables/ \
     --header 'accept: application/json'

• Show configs

curl --request GET \
     --url localhost:23820/configs/ \
     --header 'accept: application/json'

• Show variable

curl --request GET \
     --url localhost:23820/variables/{variable_name} \
     --header 'accept: application/json'

• Show config

curl --request GET \
     --url localhost:23820/configs/{config_name} \
     --header 'accept: application/json'

• Set variable

curl --request POST \
     --url localhost:23820/variables \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data ' \
{
    "{variable_name}": "{new_value}"
} '
