Add docker self-contain plugin, default share name, nobrl and cache

[jmaitrehenry]

Hi,

I made the following changes:

• Add the possibility to build a self-contain docker volume plugin
• Add default share name to volume name
• Add nobrl and cache option
• Change --verbose to -v and put it before -o in the mount instruction for some Linux (like Alpine)

I will update the readme for adding the new options.

If you want to try the plugin:

$ docker plugin install jmaitrehenry/azurefile DEBUG=true AZURE_STORAGE_ACCOUNT=xxx AZURE_STORAGE_ACCOUNT_KEY=yyy

Plugin "jmaitrehenry/azurefile" is requesting the following privileges:
 - network: [host]
 - mount: [/dev]
 - allow-all-devices: [true]
 - capabilities: [CAP_SYS_ADMIN CAP_DAC_OVERRIDE CAP_DAC_READ_SEARCH]
Do you grant the above permissions? [y/N] y
