Bump spf13/cobra to v0.0.3, pflag to v1.0.1
Use a tagged release of Cobra. All relevant PR's were merged, so the fork is
no longer needed.

Relevant changes:

- spf13/cobra#552 Add a field to disable [flags] in UseLine()
- spf13/cobra#567 Add `CalledAs` method to cobra.Command
- spf13/cobra#580 Update error message for missing required flags
- spf13/cobra#584 Add support for --version flag
- spf13/cobra#614 If user has a project in symlink, just use its destination folder and work there
- spf13/cobra#649 terminates the flags when -- is found in commandline
- spf13/cobra#662 Add support for ignoring parse errors
- spf13/cobra#686 doc: hide hidden parent flags

Also various improvements were added for generating Bash
completion scripts (currently not used by us)

Fixes usage output for dockerd;

Before this update:

    dockerd --help

    Usage:	dockerd COMMAND

    A self-sufficient runtime for containers.

After this update:

    dockerd --help

    Usage:	dockerd [OPTIONS] [flags]

    A self-sufficient runtime for containers.

Bump spf13/pflag to v1.0.1

Relevant changes:

- spf13/pflag#106 allow lookup by shorthand
- spf13/pflag#113 Add SortFlags option
- spf13/pflag#138 Generate flag error output for errors returned from the parseFunc
- spf13/pflag#141 Fixing Count flag usage string
- spf13/pflag#143 add int16 flag
- spf13/pflag#122 DurationSlice: implementation and tests
- spf13/pflag#115 Implement BytesHex type of argument
- spf13/pflag#150 Add uintSlice and boolSlice to name prettifier
- spf13/pflag#155 Add multiline wrapping support
- spf13/pflag#158 doc: clarify difference between string slice vs. array
- spf13/pflag#160 add ability to ignore unknown flags

Hide [flags] in usage output

Hides the [flags] in the usage output of commands (present in newer
versions of Cobra), using the `.DisableFlagsInUseLine` option.

Before this change:

    dockerd --help

    Usage:	dockerd [OPTIONS] [flags]

    A self-sufficient runtime for containers.

After this change:

    dockerd --help

    Usage:	dockerd [OPTIONS]

    A self-sufficient runtime for containers.
