Support maverick configuration load / save / edit

[SamuelDudley]

Maverick configuration files are JSON

Read configuration files and expose the content via graphql as name:value pairs (similar to parameters)

On save from -web archive old file and write out new one
Expose diff of JSON via graphql

[SamuelDudley]

-web related but the editor from vscode can be embedded for editing json files...

Possible to allow json comments

[SamuelDudley]

Diffs are also possible to display. Just need to load the contents of both files.

use pyinotify to watch for file changes... if not available (cloud9, vscode has taken all the file watchers) fall back to polling for changes (as per the config file of -api)

[SamuelDudley]

1. need a graphql interface for writing individual settings. (C)
2. need a graphql interface for reading individual settings. (R)
3. individual settings that already exist will be overwritten via 1 (U)
4. need a unique message for deleting settings (D)
5. need a graphql interface for reading all settings back as a list of settings.
6. need a graphql interface for writing an entire file from a the browser with md5 checks (power user mode)
7. need a graphql interface for reading all available settings and supported values. (like param meta)
8. need graphql interface for diff. changed, added, deleted
9. need graphql interface for saving files / database entry
10. need graphql interface for loading files / database entry
11. need graphql interface for deleting files / database entry
12. need graphql interface for exposing available saved files / database entries

on -api startup snapshot config files and check against what is stored in the database. If they are the same do nothing, otherwise create a new version revision.

While -api is active, changes to the config file will not create a new version in the database unless it is requested from -web or a maverick-configure is run. When -api / system restarts, any non-captured changes will create a new entry in the database.

It sounds a lot like git... consider using a pure python git interface to manage changes https://github.com/dulwich/dulwich

Note the following is a hierarchy with the top files overwriting any config set in the files below.
read the hostname, environment (~/config/maverick/maverick-environment.conf) and branch (~/config/maverick/maverick-branch.conf)
