Add wildcard support to fs copy and link actions

[maddenp-noaa]

Description

Add support for glob and regex wildcards in fs copy and link actions.

Currently, the fs config key-value pair

/dst/<foo>: /src/foo.*

would be interpreted, when fed to uw fs copy, to mean:

Copy the file literally named foo.* in the /src/ directory as a file named <foo> in the /dst/ directory.

With support for a !glob UW YAML tag, key-value pair

/dst/<foo>: !glob /src/foo.*

would be interpreted to mean

Find all files in the /src/ directory matching glob pattern foo.* and copy them, retaining their names, to the directory /dst/.

Note that the <foo> element of the destination path is discarded. It is just a placeholder and can be anything, but is necessary to support multiple key-value pairs targeting the /dst/ directory, since keys must be unique.

Source paths tagged !regex would receive the same treatment, except that the patterns would be treated as regular expressions.

The uw fs link action would behave similarly, but create symlinks instead of copies.
