Add support dump UI

This adds an option in the user pull down to generate a support dump.
While not totally ideal from a UE perspective, we don't really have
a page to do admin tasks, so this'll have to do for now.  With this
we can remove the rather ugly docs we have explaining how to get
support dumps via curl.

Non admin users will get the standard permission denied page, as with
all the other admin-only tasks we have.

-# UCP Support Dumps
-
-UCP supports generating support dumps across the entire swarm cluster,
-leveraging the dsinfo container developed by Docker Support.
-
-In this version of UCP, support dumps are only exposed via API, but this can be
-fairly easily accessed with curl.  The following example shows how to download a
-support bundle from your UCP server.
-
-This example leverages curl, which most customers should have, as well
-as a handy utility called [jq](https://stedolan.github.io/jq/).  If the
-customer doesn't have jq or doesn't want to install it, they can manually
-cut-and-paste the token output from the login command below.
-
-
-```bash
-# Replace with your UCP server IP or hostname
-UCP=https://192.68.1.2
-echo -n "Please enter your admin password"
-read -s PASSWORD
-TOKEN=$(curl --insecure -s -X POST -d "{\"username\":\"admin\",\"password\":\"${PASSWORD}\"}" "${UCP}/auth/login" | jq -r '.auth_token')
-
-curl --insecure -s -H "X-Access-Token:admin:${TOKEN}" -X POST "${UCP}/api/support" > dump.zip
-```
-
-> **Hints**:
-
->* The UCP server doesn't like extra slashes at the beginning, so if you set your UCP variable with a trailing slash, then you'll get a 301 (redirect)
-
->* The token often has special characters in it, so if the user cuts and pastes, they may run into problems with the shell interpreting things like $
-
->* If you want to avoid the --insecure, you'll have to install the UCP server's cert locally.  See below...

-
-## Trusting the UCP server
-
-If you want to trust the UCP servers certificates on the local system, you can
-use the following technique.  Note that the paths are somewhat system specific
-and may vary from linux distro to distro.
-
-Run the following when pointed at the machine the UCP server is running on
-(either locally, or via DOCKER\_HOST).
-
-```bash
-sudo bash -c "docker run --rm -it \
-        --name ucp \
-        -v /var/run/docker.sock:/var/run/docker.sock \
-        docker/ucp \
-        dump-certs > /usr/local/share/ca-certificates/orca.crt"
-sudo update-ca-certificates
-```
