feat(api): added autoexec + major type setting changes

[saadjutt01]

Fixes #117

Implementation

Server Mode:

• Any User can save/update his autoexec through APIs.
• Admin can view autoexec of all users through get single user API.

Desktop Mode:

• Admin can set autoexec content at ~/.sasjs-server/user-autoexec.sas

Contents of autoexec will be injected into code at runtime. https://github.com/sasjs/server/blob/main/api/src/controllers/internal/Execution.ts#L123
