Magnum quickstart doc swarmbay errors and missing steps

[Jaycen Grant]

In the magnum quickstart guide, there are the following errors and a missing step for correct setup:

1) In the building and using a swarm bay section, there is a missing env setup needed to support TLS. DOCKER_TLS_VERIFY needs to be set to "1"

2) In the building and using a swarm bay section, the calls to sign the CSR and download the cert are missing parameter names in the call.

magnum ca-sign swarmbay client.csr > cert.pem
magnum ca-show swarmbay > ca.pem

Should be:

magnum ca-sign --bay swarmbay --csr client.csr > cert.pem
magnum ca-show --bay swarmbay > ca.pem

3) In the building and using a swarm bay section, the command to set the DOCKER_HOST env variable is incorrect since the bay-show command includes "https://" before the ip address which is the wrong format for the variable. Needs to be updated and also include export command.
