Add new cli command to update runtime with graphql depth limit

[abhishekkumams]

Why make this change?

• Closes #2243, #2249
  • Currently CLI doesn't support updating runtime settings.
  • Need a flexible way to add/update graphQL depth limit

What is this change?

• This PR contains changes related to CLI.
• Updated the draft schema to add the new property in the runtime section.
• A new command is added dab configure, which will allow updates for non-entity based config settings.
• We have added an optional flag --runtime.graphql.depth-limit, which will be used to specify the depth limit for GraphQL queries and mutation.
• By Default, No limit is imposed.
• values supported are only integer values [1, Int32.MaxValue]. example: dab configure --runtime.graphql.depth-limit 20.

NOTE:

if limit is not already specified, it will add this property to config, else update it.

• Additionally, users can use -1 to remove limit. dab configure --runtime.graphql.depth-limit -1

How was this tested?

• [X] Unit Tests

Sample Request(s)

initial config

"graphql": {
    "path": "/graphql",
    "enabled": true,
    "allow-introspection": true
}

command: dab configure --runtime.graphql.depth-limit 20

"graphql": {
    "path": "/graphql",
    "enabled": true,
    "allow-introspection": true,
    "depth-limit": 20
}

command: dab configure --runtime.graphql.depth-limit 8

"graphql": {
    "path": "/graphql",
    "enabled": true,
    "allow-introspection": true,
    "depth-limit": 8
}

command: dab configure --runtime.graphql.depth-limit -1

"graphql": {
    "path": "/graphql",
    "enabled": true,
    "allow-introspection": true,
    "depth-limit": -1
}

Special Case: if value of "depth-limit" is null in the config. it will stay as is, if not updated.

"graphql": {
    "path": "/graphql",
    "enabled": true,
    "allow-introspection": true,
    "depth-limit": null
}

command: dab configure

No change:

"graphql": {
    "path": "/graphql",
    "enabled": true,
    "allow-introspection": true,
    "depth-limit": null
}
