[DB Access 6] Add Connect Button and Popup Dialogue

[kimlisa]

Description

For the database access table, render a button for each row that says connect, that when clicked upon, a dialogue shows up with CLI commans with most field values preopulated.

For example, given this row, and our logged in user is kimlisa and my current cluster is asteroid-sun.teleport.sh:

Name            Description                      Protocol Type        URI                                                                      Labels                  
--------------- -------------------------------- -------- ----------- ------------------------------------------------------------------------ ---------------------- ------- 
aurora          PostgreSQL 11.6: AWS Aurora      postgres rds         postgres-aurora-instance-1.c1xpjrob56xs.us-west-1.rds.amazonaws.com:5432 cluster=root,env=aws    <btn>  

Clicking on button for this row will render a dialogue:

CLI template

Step 1 is same as found in Apps and Nodes component.

For step 2 CLI template: tsh db login <db name>

For step 3 CLI template, depending on protocol:

psql (the quotes are required): psql "service=<clustername>-<db name> user=[user] dbname=[dbname]"
mysql: mysql --defaults-group-suffix=_<clustername>-<db name> --user=[user] --database=[database]

NOTE: The angle brackets are values we need to populate for user, the square bracket are values that user will need to fill out for themselves (so leave it as is).
