Install command to deploy flame

[k82cn]

Motivation

Currently, we only built docker images for session manager and executor manager; but it's not enough for end user to deploy it in a baremetal host. This feature will provide an flmctl install command to deploy flame accordingly.

Function Specification

1. Only support deploy from source code, either gihub or source code
2. The default prefix is /usr/local/flame
3. Both flame-session-manager and flame-executor-manager will be start with systemd

Solutions

Start subprocess to build and deploy package accordingly
