Support Dockerfile with arbitrary names for Docker build

[sajayantony]

Currently docker build command cannot use a Dockerfile that does not have Dockerfile as the name even if the user specifies it fully.

@sajayantony Ah yeah that's a good catch. Thanks for reporting this! We can definitely update the build command to detect arbitrary suffixes on Dockerfiles (which we already do in other places).

hmmm... what version do you have? this works for me.

We made a fix for this a while back f7c8ecf

Ahh .. it was an extension update issue.
Thanks for checking -

@chrisdias
Is there any way for the docker build command against the same file to remember the last tag that it built with so that the users don't have to types in the tag every time if its different?

[chrisdias]

no, can you open a new issue for this, describing exactly the behavior you would like to see?

[sajayantony]

Ok i've opened #93
