Alter existing users

[ChristopherRabotin]

There's currently a TODO on it, so I'll just handle that. ;)

@ReAzem , if you're happy with this commit I'll start writing tests. I think that merging in update_database_user_password with update_database_user_permissions (which currently raises NotImplementedError) makes it more similar to alter_database_admin and keeps everything in one function. Let me know.

@ChristopherRabotin This makes perfect sense. I will gladly review/merge this PR.

On another note, I would suggest you take a look at InfluxDB 0.9.0 since the way of altering users will be different. I have started adapting the lib to 0.9.0 on the 0.9.0_support branch. Maybe you would like to work on this feature for 0.9.0 too?

[ChristopherRabotin]

Cool, I'll get the tests done this week then.

Sure, I can handle that for 0.9.0 as well. I'll focus on 0.8 first though because that's the version we use at work.

[ChristopherRabotin]

Should this issue be closed since user alteration for 0.9 is in #109 ?

Yep!
