Add multiple user support for HTTP Auth

[rahul286]

Site specific

# ee auth create example.com --user=test --pass=test

# ee auth list example.com (Lists users)

# ee auth delete example.com --user=test

# ee auth update example.com --user=test --pass=mylongpassword

# ee auth whitelist create example.com --ip=1.1.1.1,2.2.2.2,3.0.0.0/8
(Future improvement can be export and import csv list of IPs)

# ee auth whitelist append example.com --ip=4.4.4.4,5.0.0.0/8

# ee auth whitelist remove example.com --ip=[2.2.2.2|all]

# ee auth whitelist list example.com (List IPs)

Global

# ee auth create global --user=test --pass=test

# ee auth whitelist global --ip=1.1.1.1,2.2.2.2,3.0.0.0/8

# ee auth list global (Lists users)

# ee auth delete global --user=test

# ee auth update global --user=test --pass=mylongpassword

# ee auth whitelist create global --ip=1.1.1.1,2.2.2.2,3.0.0.0/8
(Future improvement can be export and import csv list of IPs)

# ee auth whitelist append global --ip=4.4.4.4,5.0.0.0/8

# ee auth whitelist remove global --ip=[2.2.2.2|all]

# ee auth whitelist list global (List IPs)

Also, if you have a global auth set up, creating a site specific auth will override the global one.

Also, instead of using ee secure command like EasyEngine v3, maybe using ee auth makes more sense.
