How about instead providing a `datasette plugins --install=datasette-graphql` command?

Or `datasette install datasette-vega`

It would run `pip install` in the same virtualenv as Datasette itself.

http://jelly.codes/articles/python-pip-module/ shows how to do this:

```python

import pip

try:
    pip.main([""install"", ""plumbum""])
except SystemExit as e:
    pass

It worked! And from digging around, it has a virtual environment at `/usr/local/Cellar/visidata/1.5.2/libexec/`

Which means `/usr/local/Cellar/visidata/1.5.2/libexec/bin/pip` is a working `pip`

And I tried running these commands and confirmed that I get a `datasette` with an additional plugin:

```
/usr/local/Cellar/visidata/1.5.2/libexec/bin/pip install datasette
/usr/local/Cellar/visidata/1.5.2/libexec/bin/pip install datasette-graphql
/usr/local/Cellar/visidata/1.5.2/libexec/bin/datasette plugins
[
    {
        ""name"": ""datasette-graphql"",
        ""static"": false,
        ""templates"": true,
        ""version"": ""0.11"",

            ""register_routes"",
            ""startup""
        ]
    }
]
```
So I can package Datasette as a homebrew package AND I can give people instructions for installing plugins.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",339505204,
